I had decided to stop blogging until I had something fresh to share, rather than continue to re-hash the daily work and processes that take place in the shop. If you are still around and thirsting for information, here is a bit of an oasis for ya...<br />
<br />
This project kicked off just after the 2017 Philly show. Drew, Gary and I packed up from the Expo then headed over to Engin headquarters to get started on the build. Gary had shipped some vintage USA made Ancotec tubing over and now it was time to create a "bicycle shaped object" out of it. I could only hang out for one of the three days, but enjoyed my time with these two, watching Gary's dream ride come together. <br />
<br />
The raw product arrived at Groovy headquarters just before Nahbs, unfortunately, it took a back seat to other promised work. Gary was quite patient, having sat in our positions in the past, empathetic if not a bit surly :)<br />
<br />
The original request was for a single color ceramic finish in OD Green. Y'all know me, I just could not let it out of the shop with something so un-inspiring, so after a bit of cajoling, Gary agreed to let me have a go with something that was more creative. His steering focus was that the finished product should look like a war torn weapon that had just returned from service in Kuwait. Yeah, I think I can do that...<br />
<br />
I started off with about 4 hours of graphic work in Adobe Illustrator to get all my masking drawn up and then it was off to the blast cabinet. Here's a shot of the Ti frame with the masked artwork applied, post blasting and chemical wash.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://4.bp.blogspot.com/-nH2qECFD4ZM/WzpKv3pwdzI/AAAAAAAAHp8/LdlpWcE-qRkqnAHZnz7zzTaEWqGibEwJQCLcBGAs/s1600/IMG_4872.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://4.bp.blogspot.com/-nH2qECFD4ZM/WzpKv3pwdzI/AAAAAAAAHp8/LdlpWcE-qRkqnAHZnz7zzTaEWqGibEwJQCLcBGAs/s400/IMG_4872.JPG" width="400" /></a></div>
<br />
Next up was the first of seven different colors of ceramic...the beige is to be the base that the rest of the work is built off of. After mixing the catalyst with the base, it is all run through a micro screen to ensure that it is particulate free once it hits the HVLP gun...<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://3.bp.blogspot.com/-MzCrG0KKdtc/WzpKwdu2gbI/AAAAAAAAHqA/s5cSl3NkTpUbLj82X3mkdt4aZoKFXf2fQCLcBGAs/s1600/IMG_4874.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1600" data-original-width="1200" height="400" src="https://3.bp.blogspot.com/-MzCrG0KKdtc/WzpKwdu2gbI/AAAAAAAAHqA/s5cSl3NkTpUbLj82X3mkdt4aZoKFXf2fQCLcBGAs/s400/IMG_4874.JPG" width="300" /></a></div>
<br />
The base layer applied. Here at the down tube graphics, you can see just how thin ceramic applies with even coverage when done with a practiced hand.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://1.bp.blogspot.com/-qSjeekSIYUM/WzpKvGkBZYI/AAAAAAAAHp4/_YnYY7_TW68ccmyeH1Wcses4e017v5wvACLcBGAs/s1600/IMG_4876.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://1.bp.blogspot.com/-qSjeekSIYUM/WzpKvGkBZYI/AAAAAAAAHp4/_YnYY7_TW68ccmyeH1Wcses4e017v5wvACLcBGAs/s400/IMG_4876.JPG" width="400" /></a></div>
<br />
I then grabbed some grey cerakote, reduced it down, and began to spray through some mesh to create a scale effect. The intent is to cover the entire frame with a two color pattern...<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://3.bp.blogspot.com/-fJtxS6XAax0/WzpKxJkot_I/AAAAAAAAHqE/ZE9-J8RXVhIq6Zg2tYPrwDosjctaTGNtgCLcBGAs/s1600/IMG_4877.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://3.bp.blogspot.com/-fJtxS6XAax0/WzpKxJkot_I/AAAAAAAAHqE/ZE9-J8RXVhIq6Zg2tYPrwDosjctaTGNtgCLcBGAs/s400/IMG_4877.JPG" width="400" /></a></div>
<br />
I then followed up with OD Green using a different mesh pattern to give some diversity and visual texture...<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://4.bp.blogspot.com/-I6sQqG3V-L0/WzpKyuy5eHI/AAAAAAAAHqI/P68CEc3TeUo8nGXBm3YlXBsa9zTY5B0ywCLcBGAs/s1600/IMG_4878.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://4.bp.blogspot.com/-I6sQqG3V-L0/WzpKyuy5eHI/AAAAAAAAHqI/P68CEc3TeUo8nGXBm3YlXBsa9zTY5B0ywCLcBGAs/s400/IMG_4878.JPG" width="400" /></a></div>
<br />
Here's a shot with the entire frame patterned...<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://4.bp.blogspot.com/-3xuhJD0RWVw/WzpKzMvbdiI/AAAAAAAAHqM/JKZ6Rl1S5GA-z2QaYEujiFtgYe-u00xxgCLcBGAs/s1600/IMG_4879.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://4.bp.blogspot.com/-3xuhJD0RWVw/WzpKzMvbdiI/AAAAAAAAHqM/JKZ6Rl1S5GA-z2QaYEujiFtgYe-u00xxgCLcBGAs/s400/IMG_4879.JPG" width="400" /></a></div>
<br />
After a short 10 minute bake cycle and cool down, it is now safe to apply the next round of masking. In this case, I drew about 30 different "tear" patterns and then cut them in three sizes so that the entire frame could be used. It is important to apply the patterns all in the same positional orientation so that there is consistency. <br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://1.bp.blogspot.com/-kYvSY9SFx5Y/WzpKzyBvr0I/AAAAAAAAHqQ/UhD7VrhJNtoGJEao5cHuIOy4cLtuBQhyACLcBGAs/s1600/IMG_4881.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://1.bp.blogspot.com/-kYvSY9SFx5Y/WzpKzyBvr0I/AAAAAAAAHqQ/UhD7VrhJNtoGJEao5cHuIOy4cLtuBQhyACLcBGAs/s400/IMG_4881.JPG" width="400" /></a></div>
<br />
After the masks are applied the top colors go on, in this case, a dark flat earth for the overall tone with two additional custom mixed gradients for low lights. I then thinned an Armor black ceramic and shadowed in the outside perimeter of each mask...took a contortionists flexibility to get to them all without over spraying onto unwanted areas. <br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://4.bp.blogspot.com/-L-l1JGhaO14/WzpK1Y2aTHI/AAAAAAAAHqU/ZQ3m-K6n8H02k1A9NXrXa9YDSxLE9cQ7wCLcBGAs/s1600/IMG_4883.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://4.bp.blogspot.com/-L-l1JGhaO14/WzpK1Y2aTHI/AAAAAAAAHqU/ZQ3m-K6n8H02k1A9NXrXa9YDSxLE9cQ7wCLcBGAs/s400/IMG_4883.JPG" width="400" /></a></div>
<br />
Another partial bake cycle and then it's time to remove our masking to get an idea of the final visual effect...<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://1.bp.blogspot.com/-RCgUyvriIKo/WzpK16toZDI/AAAAAAAAHqc/HJahD49bQxMRVOJIHs8BptgwVYpV0_MQwCLcBGAs/s1600/IMG_4884.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="300" src="https://1.bp.blogspot.com/-RCgUyvriIKo/WzpK16toZDI/AAAAAAAAHqc/HJahD49bQxMRVOJIHs8BptgwVYpV0_MQwCLcBGAs/s400/IMG_4884.JPG" width="400" /></a></div>
<br />
The final step was to take three different materials and gently rub over the frame to provide some edge break for the raw titanium sections and a bit of a "worn" look to the ceramic areas. A final pass through the bake box and here's our final product...<br />
<br />

<br />
Gary had no idea what the finish would be, desiring to be surprised upon unpacking. This is always an nervous couple of days for me as I hope the customer loves the outcome. I didn't hear from him for almost 24 hours after receiving it...torture. Did he hate it? What the hell is going on?<br />
<br />
Finally, at 0200 our time I received a brief text.<br />
<br />
"Holy Fuck, yeah!"<br />
<br />
Good enough for me :)Rodyhttp://www.blogger.com/profile/05660584179451474241noreply@blogger.com0tag:blogger.com,1999:blog-5472444264193571913.post-72871596778886270622017-10-29T09:00:00.001-07:002017-10-29T09:00:05.363-07:00How to build a titanium handlebar...Hey folks, want to take a look inside the process of building a titanium bar? <br />
<br />
Follow along in the video as I put together one of my titanium Dig It bars; a 2" rise bar with a 31.8 center clamp section, 17 degree sweep.<br />
<br />
A few tiny things to note...<br />
<br />
- Ti has to be meticulously clean to weld, so many of the preparation steps are outlined within<br />
<br />
- Ti must be welding in an oxygen free environment with controlled heat input<br />
<br />
- You must have fun!<br />

<br />
<br />
I've received a lot of sponsorship requests through the years, many from young aspiring racers who want support, but lack understanding that it needs to be a mutually beneficial relationship. Let me give you an example of one that came in this week...<br />
<br />
<span style="background-color: white; color: #212121;"><span style="font-family: Arial, Helvetica, sans-serif;">Hey there I am (name redacted) from North Carolina currently I am a xc and gravel racer and I saw your company and I was wandering if you could sponser me with some demo or prototypes and I can test them and promote and tell many riders and fans at my races. Thanks and have a wanderful day!</span></span><br />
<span style="background-color: white; color: #212121; font-family: wf_segoe-ui_normal, "Segoe UI", "Segoe WP", Tahoma, Arial, sans-serif, serif, EmojiFont; font-size: 15px;"><br /></span>
Though well intentioned, I hope you can begin to see the plethora of issues with the request. <br />
<br />
Let me share with you my reply to this inquiry as it begins to offer a look from my side of the potential relationship. <br />
<br />
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;">Thanks for reaching out, I appreciate that you want to help represent my work.</span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;">I've sponsored a race team and individual racers for over 20 years, and have participated in race promotions for 10. This fall marks my final season participating in both endeavors, as I am scaling back to spend more focused time in the shop.</span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;">I receive multiple requests each month for sponsorship. Please let me share a bit of my experience with you so that you may have a greater probability of finding success.</span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><b>Use appropriate grammar, punctuation, and spelling.</b> When asking a company for sponsorship, you are effectively representing their products and company as a whole with the public. Affirming that you are well spoken, intelligent, and provide a positive image is important. This all begins with your sponsorship request. If you don't take the time to ensure accuracy in written word, you are not someone a company would feel confident about in the field.</span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><b>Show that you know a company's products and why you are excited to represent them.</b> No one likes quickly penned form letters; giving some indication that you know the companies product range, expected market, and how you fit into that marketing plan will give you greater odds of gaining support. Express what products the company makes that you feel would be of benefit for you to share experience and information with others. Why are you excited about those products? What tangible impact can you make on company exposure and sales? </span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><b>Why you?</b> Thousands of racers hit the starting line each week, what makes you exceptional? Provide race results and give some demographics showing the area you frequent in your travels. While exposure to the podium is important, it is not the defining criteria for support. Companies want racers who represent their vision and are willing to be an advocate. Is this something you are capable of? If so, tell them why.</span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><b>Finally, begin a relationship with your prospective sponsors.</b> Show that you are not just shotgunning out requests hoping for getting lucky. Purchase one of their products, write a review, send pictures of the product in use...companies will more likely support a young racer who support them and have a measure of positive influence on others.</span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="background-color: white; margin-bottom: 0px; margin-top: 0px;">
<span style="font-family: Arial, Helvetica, sans-serif;">Good luck in your search for sponsorship, I know that if you heed some of this advice, you will find success.</span></div>
<div>
<br /></div>
<div>
It's rare to get something for nothing. It becomes more probable when you can demonstrate a willingness and ability to positively work for the support. Mentor, educate, share...perhaps we'll all get more out of future requests.</div>
<div>
<br /></div>

Given enough time, wind, cycles, wear, exposure, stress, eventually a change takes place. I mean, that's how we have the Grand Canyon, survival evolution, and broken bicycle parts.<br />
<br />
Wait, what? Bike parts don't last forever?<br />
<br />
That's right, I know it's hard to accept, but any material, when placed in a stressful environment, with repeated impact cycles, will eventually fail. <br />
<br />
Yes, I agree, that sucks.<br />
<br />
You see, the hurdle with designing bicycle parts is cutting that delicate balance point between performance, light weight, and durability for a wide range of physical users parameters. Often, the same part that is used by a buck twenty female on a full suspension rig, cruising a flow trail, is also under a 220# guy riding fully rigid on rocky/rooty single track. Where is the line drawn that divides durability with performance expectations, and takes into account your business needs for streamlining inventory and production? It's hard to pin down, but we can come close. Products are tested using FEA models, destructive testing of sample products takes place, and fabrication sequences are formulated to optimize and perfect the process. All in an effort to stack the deck in our favor. In the end, all this data is evaluated, but for each builder, the unique end point is different. <br />
<br />
This is prominent in my attention span today because I've just had my fifth handlebar failure in 12 years (3 titanium, 2 steel). Bar failures are the worst. Just like a chair, if you remove one of the four points of contact without notice, you'll be tumbling over quickly. Now imagine cruising down a rooty single track hill when suddenly one of your hands is now floating free. Not good. Not good at all.<br />
<br />
One of my greatest fears when opening my email each day is to find a communication from a customer who has suffered a failure with a resultant injury. To think that a product I produced, intended to enrich the lives of the customer, one day results in a physical injury, truly unsettles me. There's a level of trust that is unspoken; that I will make my best effort to provide a product that delivers fun and enjoyment, doing so in a safe, predictable manner.<br />
<br />
The problem, though, is in that last line. In the niche of mountain biking, there is nothing that is sure fire predictable. The variables are broad. The risk is real. Try as I may, I cannot control all the variables that my products are exposed to. <br />
<br />
The customer bears a burden of responsibility as well. Proper installation, maintenance, inspection during cleaning...all of these are part of the due diligence the customer accepts as an end user. In a Utopian world, one hopes that product deficiencies are recognized early and the part taken out of service. That is, unfortunately, rarely the case. Even in Utopia, however, the tough fact to accept, is that despite both of our efforts, every part has a fatigue life and will eventually fail. Period. The End.<br />
<br />
From a builders standpoint, this is why you MUST HAVE INSURANCE. It is not for protecting you from potential liability, you've already shouldered that burden when you chose to hang out your shingle and accept money for your work. It is for the protection of your customer when things do not go as intended.<br />
<br />
Each time I am made aware of a failure, I second guess my desire to continue in this field. Though the percentage of failures to living product is minuscule, the shear burden of potential is a heavy load to carry moving forward. Despite how diligent I am in design and execution, how attentive the customer is to maintenance and inspection, the product will eventually reach an end of life point. When that happens, I pray no one is injured severely. <br />
<br />
The final decision, for builder and customer alike is this; what level of risk is acceptable to you?<br />
<br />

Life is fragile and horrible accidents take place around us each day. I guess, for me, I am driven to create and share because of the positive impact it has on others. As a rider, I would not want to envision a life where cycling was not an integral part. So, is the risk worth it? I'm choosing to soldier on, with vigor, because these aspects define much of who I am.<br />
<br />
What is your decision?<br />

<br />
I've always enjoyed watching evolving technology and have wanted to incorporate some old tech into new projects, so I built Kalten a Nixie tube clock.<br />
<br />
Nixie tubes were developed in the 1950's, a precursor to digital displays. It is a cold cathode electrode inside a glass tube filled with neon gas and just a touch of mercury. The numerical cathodes are stacked using ceramic insulators and when electricity is passed to the electrode, it reacts with the neon gas and glows, displaying the number.<br />
<br />
There is still a small supply of these tubes in the Eastern Block countries, as they manufactured them into the early 80's. <br />
<br />
I sourced the tubes from Russia, the board from a gentleman in the Ukraine, and then got to soldering.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://4.bp.blogspot.com/-zpjU_GtH7rQ/WVkCSuJjYGI/AAAAAAAAHm4/0ZiXh3_85_MTAsTHt2RFGM_zrQVcafnPACLcBGAs/s1600/IMG_3082.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="1600" height="240" src="https://4.bp.blogspot.com/-zpjU_GtH7rQ/WVkCSuJjYGI/AAAAAAAAHm4/0ZiXh3_85_MTAsTHt2RFGM_zrQVcafnPACLcBGAs/s320/IMG_3082.JPG" width="320" /></a></div>
<br />
The clock allows for 12/24 hour time display, date, and alarms. I placed RGB Leds under each tube and the color changes during use.<br />
<br />
The case is built out of sheet metal and was finished in an antique/distressed paint theme.<br />
<br />
Came out pretty cool, makes me want one for myself :)<br />

This year I had the pleasure of hosting Daan from <a href="http://www.11antsbikes.com/" target="_blank">11 Ants Titanium Bicycles</a>. The owners have focused their bicycle design
on Pinion and Rohloff builds in titanium, a market segment that has room for
growth in Europe. Their builds for the
last three years have been commissioned in China, but due to the stresses of
working long distance and inability to control quality, spec, and manage
expectations, they want to move the production home to Holland. Daan came to me with 20 years fabrication and
machine shop experience, but no bicycle work.
It was our goal to expose him to the fabrication process and begin to
understand the unique difficulties in working with Titanium.<o:p></o:p></div>

So, here's a quick post just to see if anyone is still out there...<br />
<br />
Spent the better part of the last two weeks knocking out January/February bar orders and crafting up some tasty titanium cranks...<br />
<br />
Much like welding a frame, the bars have a systematic welding process to keep them aligned and flat, starting with the linear ends of each miter<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://2.bp.blogspot.com/-uLSwc0CCH7U/WJ8sC2YawvI/AAAAAAAAHlk/_wUxP4V8GqISykEDanAWL925Rfal2ChQwCLcB/s1600/Titanium%2BLuv%2Bon%2Bthe%2Bway%2B2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="https://2.bp.blogspot.com/-uLSwc0CCH7U/WJ8sC2YawvI/AAAAAAAAHlk/_wUxP4V8GqISykEDanAWL925Rfal2ChQwCLcB/s320/Titanium%2BLuv%2Bon%2Bthe%2Bway%2B2.jpg" width="320" /></a></div>
<br />
<br />
The bars are the only titanium item I single pass weld, as the additional heat of a two pass process becomes a bit more problematic with alignment. To ensure complete penetration, a higher energy setting is used with a brief pulse to drive the arc deep into the substrate and feather out a bit wider than normal...<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />

<br />
<br />
These titanium cranks are ran through the blast cabinet so that it will provide a mechanical surface for the ceramic to adhere to...<br />
<br />

<br />
<br />
Colored and ready for action 3 hours later...<br />

Often this tooling is designed with a range of variability so that minor changes in design can be accommodated.<br />
<br />
Production work, however, necessitates that dedicated, fixed position equipment be used to ensure accurate, repeatable results from piece to piece. <br />
<br />
Today, I want to talk about the importance of "soft jaws". Soft jaws are replaceable tooling that hold a part for machining, often not heat treated, allowing the operator two distinct advantages; the ability to shape the jaws to perfectly fit the piece being machined. Secondly, the shaped clamping surface provides greater surface contact allowing for a less robust clamping surface, leaving no impressions on the finished part.<br />
<br />
The example we are going to look at here is a set of jaws that were shaped to accept the spider interface for the Hot Rod cranks. In this case, the part is water jet cut to the rough dimensions and the center hole needs to be opened up to 24.02 mm and then face relieved a skoosh so that it is a tight slip fit over the bottom bracket spindle.<br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>
<tr><td style="text-align: center;"><a href="https://3.bp.blogspot.com/-S3gJ6zOO41g/Vs3FcwsaoPI/AAAAAAAAHhg/hSVHzfcjfwM/s1600/softjaw%2B1.JPG" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="240" src="https://3.bp.blogspot.com/-S3gJ6zOO41g/Vs3FcwsaoPI/AAAAAAAAHhg/hSVHzfcjfwM/s320/softjaw%2B1.JPG" width="320" /></a></td></tr>
<tr><td class="tr-caption" style="text-align: center;">The base part, before machining</td></tr>
</tbody></table>
To place this part into a standard set of pointed hard jaws in a lathe makes concentricity difficult to attain part to part, as there is minimal surface contact between the jaws and the part to be machined. I used a tool post grinder, mounted to the cross slide, to create a shaped opening in the face of the jaws, allowing me to have a surface that holds the part perfectly flat and concentric to the spindle for machining.<br />
<br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>
<tr><td style="text-align: center;"><a href="https://4.bp.blogspot.com/-17mPqu5rJGs/Vs3FdIB8R6I/AAAAAAAAHhk/jiaLvkX9kUY/s1600/softjaw%2B2.JPG" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="240" src="https://4.bp.blogspot.com/-17mPqu5rJGs/Vs3FdIB8R6I/AAAAAAAAHhk/jiaLvkX9kUY/s320/softjaw%2B2.JPG" width="320" /></a></td></tr>
<tr><td class="tr-caption" style="text-align: center;">The lathe jaws, ground to accept the part</td></tr>
</tbody></table>
This shaping of the jaws permits a consistent origin point from which to begin the machining process, and contacts a majority of the outer surface leaving no clamping impression, therefore meeting our goals.<br />
<br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>
<tr><td style="text-align: center;"><a href="https://2.bp.blogspot.com/-6rywru5dSW0/Vs3FdfsDPyI/AAAAAAAAHhs/XPPYYHY2z7E/s1600/softjaw%2B5.JPG" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img border="0" height="240" src="https://2.bp.blogspot.com/-6rywru5dSW0/Vs3FdfsDPyI/AAAAAAAAHhs/XPPYYHY2z7E/s320/softjaw%2B5.JPG" width="320" /></a></td></tr>
<tr><td class="tr-caption" style="text-align: center;">The part clamped and machined in the soft jaw</td></tr>
</tbody></table>
Whether in a vice, lathe, or in a fixture, precision soft jaws created for the operation are an asset to the fabricator and should be considered for any production piece.<br />
<br />

The ironic twist with the niche of frame builders is that our numbers are so small, often pros, </span>hobbyists<span style="font-family: inherit;">, and lurkers share the same space. Professionals who desire to mentor, share, and encourage others to begin the journey to mastery, struggle with how to set standards for acceptable practices. Keeping "the bar raised" on what is to be considered the standard for quality is no easy task.</span><br />
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">The issue with the internet, is that misinformation spreads like wildfire. "Experts" are born behind a keyboard and within a short time, are establishing facts that are anything but, only to have others pass it on. The crux is when an experienced pro who knows better attempts to correct the misinformation, only to be barraged with negativity. Soon, the experienced mentors retreat to their shops, frustrated and unwilling to make the effort again. This is how the loss of knowledge begins in today's classroom of zeros and ones.</span><br />
<span style="font-family: inherit;"><br /></span>
<span style="color: #333333; font-family: inherit;">Enough time has transpired through many list serves/forums/pages that it has become clear to me that one can never remove the human element of ego and need for affirmation from discourse, regardless of the subject. Moderation can provide some constraint, but will never re-direct those who refuse to acknowledge or conform, regardless of the experience or knowledge possessed by those offering assistance. </span><br />
<span style="color: #333333; font-family: inherit;"><br /></span>
<span style="color: #333333; font-family: inherit;">The best way to "keep the bar high" and provide the level of mentoring we wish to convey is to be the one on the field keeping the bar in place, setting the professional example. It takes time to be a presence, guide, mentor via the interwebs, and each of us must decide if that is within themselves to share and provide at the cost of time, frustration, and little thanks. </span><br />
<span style="color: #333333; font-family: inherit;"><br /></span>
<span style="color: #333333; font-family: inherit;">A unified presence/effort by those that want to make a difference and see standards set is the tool to get this job done.</span><br />
<span style="color: #333333; font-family: inherit;"><br /></span>
<span style="color: #333333; font-family: inherit;">I'll continue to add my voice where appropriate and hope for a chorus and not an echo.</span><br />

This time, however, it is not driven by a big corporation wishing to redevelop a standard to sell more of their branded components, it's origins lie among a small frame builder, a family owned component company, and the man who has been responsible for the explosion in frame building today by developing more high quality fiddly bits and offering them for sale, than any other.<br />
<br />
It began one year ago, at the Philly Expo, when a conversation between a customer and a builder blossomed into a discussion on what needed to improve upon the bicycle as we know it. At the crux of the conversation, the inadequacy of most frame builders to accurately create a high tolerance, well machined interface for the press fit 30 bearings, and therefore, the erosion of consumer confidence in the standard.<br />
<br />
Once you've been in this industry long enough, you begin to see "trends" come around a time or two. The complaints about the press fit 30 bottom bracket ring through the air; the bearings must be pressed in with a special tool, after use they can creak and make noise, bearings fail more rapidly, they are hard for consumers to work on, etc... Anyone remember Klien, Fat Chance, and a few others? Pressed in bearings that gave people fits and subsequently went back to threaded interfaces...here we go again.<br />
<br />
Let me introduce the T47 bottom bracket; a piece that begins with the same inner diameter as the press fit 30 and then adds threads. Isn't this just a bigger standard English bottom bracket? Nope, let me explain why...<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://2.bp.blogspot.com/-QKzc3d54BSc/VkKhfRsbhbI/AAAAAAAAHfk/hkaKLqCZhFs/s1600/T47.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="271" src="http://2.bp.blogspot.com/-QKzc3d54BSc/VkKhfRsbhbI/AAAAAAAAHfk/hkaKLqCZhFs/s320/T47.jpg" width="320" /></a></div>
<br />
The T47 has the following positive attributes:<br />
<br />
- uses a larger shell to allow oversized diameter tubing to match without swaging<br />
- the shell is thick enough to allow welding of both steel and titanium without distortion<br />
- the threads are properly sized to facilitate hand tapping post fabrication and for maintenance<br />
- the bb shell will allow cups to fit all current crank spindle sizes<br />
- existing frames with press fit 30 metallic shells can now be reamed and tapped with threads, prolonging their lifespans of use<br />
- at least three bottom bracket manufacturers are already producing parts for this spec, so parts will be available<br />
<br />
The T47 has the following negatives characteristics:<br />
<br />
- weighs slightly more than a standard English bottom bracket shell of the same width<br />
- builders will have to purchase new taps and make tooling accommodations<br />
- people who like to grumble have another opportunity to do so<br />
<br />

<br />
I've been fortunate to have known of this for quite some time and I'm in favor of it. I like the fact that if I include it in a build, it allows the customer to have options in the future. I like the fact that it will save some frames already equipped with noisy pf30 shells. I like the fact that a certain headset maker whose product I love will be making their first bottom bracket to match this spec. I like the fact that I have a shell in my hand to build one of the first bikes...off to the shop to start making plans.Rodyhttp://www.blogger.com/profile/05660584179451474241noreply@blogger.com0tag:blogger.com,1999:blog-5472444264193571913.post-59714039769193666762015-09-25T07:08:00.006-07:002015-09-25T07:08:52.685-07:00What does it mean to race?<div class="MsoNormal">
“So are you riding in Dr. Knob’s Malevolent Team Challenge
on October 10th?”<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
It’s a question I’ve asked a lot of folks as the date draws
near. Some respond with an enthusiastic “YES,
can’t wait!”, but many give me an automatic response… “No, I’m not a racer, I
just enjoy riding for fun.”<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
That’s disappointing, let me share why.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Whether the trails you enjoy riding are privately held or on
public land, the monetary burden of maintaining these trails often falls to
local volunteer groups who have embraced the effort of maintaining and improving
the trail systems to the benefit of all.
Though their time is given freely, tools, materials, insurance, and
requisite permits/fees are not. That
money has to come from somewhere. With
government budgets under the scrutiny of the public eye, that money must often be
generated by private groups who care enough to see the trails thrive. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Here in Ohio, revenue is commonly the result of
participation in our local races. 331
Racing and the OMBC both host races on private/public trail systems with
proceeds from the race fees returning to the venues to be used by the local
advocates. Your race dollars are going
back into the trails you are gliding across, administered by the folks who care
the most about them. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In the case of Vulture’s Knob, we toe a very tight financial
line. Unlike public lands that have the
ability to include rider liability into their overall insurance policies,
funded by a large tax base, this property must stand alone and pay for its
participants each season. We generate
income through two primary revenue streams; donations and race
participation. Donations yield about $1500.00
a year, leaving a gap of approximately $8500.00 annually to cover insurance,
utilities, maintenance, and any improvements we wish to make to the trail
system. That’s no small potatoes.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
I implore you, re-define your perspective on what it means
to participate in your local races. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Some race to set performance goals, push physical limits,
and compete; it’s about going fast and we welcome that.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
There is, however, another relevant perspective; racing is
an element of community participation and support. It’s part of a movement to support your trail
systems, creating a sense of advocacy, ownership, and contribution to a larger
goal. Race participants are the
financial backbone of many of our trails, creating recreational opportunities
for all to enjoy, from cradle to grave. Regardless
of whether you stand upon the podium or just finish with a smile, race
participants are stewards of our trails.
<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
For us, it’s about giving back to something you believe in. Vulture’s Knob allows us to share our love of
mountain biking with others in a way that is unique, special, and is held
tightly in our hearts.<o:p></o:p></div>

That makes riding difficult if not down right uncomfortable.<br />
<br />
You need two distinct forces to remove a stuck stub of post; mechanical and temperature.<br />
<br />
I've never met a stuck post I could not remove yet, so though I don't relish these fixes, they are strangely alluring in their challenge.<br />
<br />
Here was a walk down memory lane for a stuck Thomson...<br />
<br />
<a href="http://groovycycleworks.blogspot.com/2009/01/friday-was-repair-day.html" target="_blank">Stuck Thomson post...</a><br />
<br />
This ti post gave up the fight pretty easy though.<br />
<br />
First thing I did was look to gaining some mechanical force. Trying to grab the stub with a pipe wrench or other "crimping" style tool will only ovalize the tube and create pressure on the inside of the seat tube, increasing the difficulty of removal. So I drilled a through hole in the remaining material that allowed the passage of a 5mm allen tool that I would then use as a lever to turn and lift with.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-7JvjaESlpi4/VdXkUXHYhgI/AAAAAAAAHe0/SdutApHN0yo/s1600/Pauls%2Bpost%2B1.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://1.bp.blogspot.com/-7JvjaESlpi4/VdXkUXHYhgI/AAAAAAAAHe0/SdutApHN0yo/s400/Pauls%2Bpost%2B1.JPG" width="300" /></a></div>
<br />
Next, I applied heat to the inside of the post in it's full diameter; enough to create some expansion of the seat tube and loosen the potential corrosion, but not enough to affect the paint.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-mikhSbMXY8o/VdXkUjrgogI/AAAAAAAAHfM/8n7KfVOewhI/s1600/Pauls%2Bpost%2B2.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://4.bp.blogspot.com/-mikhSbMXY8o/VdXkUjrgogI/AAAAAAAAHfM/8n7KfVOewhI/s400/Pauls%2Bpost%2B2.JPG" width="300" /></a></div>
<br />
Then it was a simple twist and pull with a few choice words when I cut my finger on the ragged edge of the broken post.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-vslo1EwAqjA/VdXkUhC8m_I/AAAAAAAAHfE/09eQndBp3Ig/s1600/Pauls%2Bpost%2B3.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://4.bp.blogspot.com/-vslo1EwAqjA/VdXkUhC8m_I/AAAAAAAAHfE/09eQndBp3Ig/s400/Pauls%2Bpost%2B3.JPG" width="300" /></a></div>
Wah-lah...<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-j6pIcaWwAPY/VdXkVGr0PKI/AAAAAAAAHfQ/_QHDv89BxTE/s1600/Pauls%2Bpost%2B4.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://4.bp.blogspot.com/-j6pIcaWwAPY/VdXkVGr0PKI/AAAAAAAAHfQ/_QHDv89BxTE/s400/Pauls%2Bpost%2B4.JPG" width="300" /></a></div>
<br />
Inspection of the post showed that there was a distinct discoloration inside the wall of the tube about 1/8" long, possibly a defect during the drawing of the material. Who knows, just glad that Paul is Okie Dokie and that the bike will now be on the trail again soon.<br />
<br />

You see, most mills, lathes, etc that you find available are surplus or outdated industrial equipment equipped with 3 phase motors, whereas most home shops/garages are single phase power only.<br />
<br />
So, how do we power this new toy?<br />
<br />
What most folks first consider is "simply" replacing the motor with a single phase unit. While possible, this is seldom a good option due to the necessity of fabricating custom motor shafts, pulley adapters, or mounting brackets; all timely and frustrating hurdles to get your machine up and running. <br />
<br />
A popular option is a static phase converter, an in-line piece of equipment that is only activated when the machine is started. Priced from 100 - 500 dollars dependent on motor size requirements, this will get your machine up and running, although at a reduced/loss of power around 2/3rd of it's rated horse power. While effective, the disadvantage is that you must purchase a static phase converter for each piece of equipment you wish to power.<br />
<br />
The option I want to share today is using a idler motor as a integrated piece of electrical equipment to provide the requisite power requirements for your new machine. <br />
<br />
A single three phase motor can be wired into your system as a rotary phase converter. This is accomplished because a three phase motor can be run off two poles, allowing the third pole generated from the idler motor to be fed back into the machine circuit. This will provide an unbalanced three phase power that will allow your machine's motor to run at full capacity. When wired into your machine circuit, this single converter can be used to power all your machines simultaneously. The disadvantage...you have to provide some type of mechanical force to start the idler motor turning (pull start) and your energy consumption will be higher as you will be essentially running two motors during machine operation.<br />
<br />
I like to have an idler motor that is 20- 30% larger than that of the highest rated HP motor in your machines if you want to run multiple pieces of equipment. For example, if you have a machine with a 5 hp motor, look for at least a 7 hp idler.<br />
<br />
Use a good quality motor. I like Baldor motors for their smooth bearings and quality build. The motor will have an information plate which tells not only it's specifications, but also the appropriate wiring configuration...<br />

<br />
I typically turn down a piece of aluminum round stock to fit over the motor spindle, machine in a keyway, and then glue a piece of automotive rubber hose over the whole shebang. This allows me to wrap a flat piece of webbing tightly around the spindle to give it a smooth pull and get the motor running...<br />

<br />
<br />
In this case, we are using low voltage connections. There are a total of three wires leaving our panel , going to the idler motor (red, black, green). Our two power leads (red and black) will power the motor once it is spinning. So using this chart, our Red lead will attach to wires 7/1, our black lead will attach to wires 2/8, wires 4/5/6 are bundled together, and our green ground to the motor ground. The White wire, left out from our initial run, will then <b>leave</b> from the motor after attaching to wires 3/9 and go out to the breaker in the panel for our machines. Coupled with the other two power leads, the idler motor generates the third pole that our machines will use.<br />

<br />
<br />
To use, I simply wrap and pull the motor spindle in the correct direction of travel, turn on the breaker or disconnect switch to keep it running, and then the machines already wired in the shop circuit have the capacity to work all day on generated three phase power.<br />
<br />
Note, there are comprehensive guides available online to help you set up an electrical system to meet your 3 phase needs. This is intended only as an awareness piece, not a "how to" guide. If in doubt, contact a licensed electrician to help discern your shop needs.<br />

The question distilled down: ...is it a viable business plan to build factory spec frames in
batches and how can one best market/partner with shops to create a
streamlined product line without the intensive time involved in one-off
building.<br />
<br />
I learned in what I would consider a small batch production facility
that also did custom work in limited numbers. The basic structure I
will share is what provided a successful business that supported 4-5
families for many years. The key, like any successful business, is
having a well thought out plan with known COGS, production capability,
and defined marketing plan.<br />
<br />
In short, here are the key elements:<br />
<br />
Your production frames need to have defined geometries and sizing that
land solidly into the physiologic standards accepted by the industry but
have your personal vision/interpretation of performance
characteristics. Your perspective on how a bike should "feel" and
handle should transfer through the experience to the rider. We found a 4
product size range to meet 95% of our needs...beyond that, it became
time intensive helping define the fit for the customer.<br />
<br />
The frame design and the tubing/components used need to be readily
available or stocked in ample supply to maintain a consistent work pace.
Using component design, such as dropouts, gussets, etc..., that allow
for use across the entire size range is imperative as it eases
fabrication and increases efficiency in both manufacturing and cost.
These items should also speak to your identity, creating an aesthetic
that differentiates you from other brands on the floor. <br />
<br />
The majority of your capital investment will be in creating dedicated
fixtures for each model to expedite the fabrication process. Time spent
fiddlefucking around with machine set up is money lost. Invest in
being prepared for efficient/repeatable work flow.<br />
<br />
Standard finishes that are distinctive and easily created need to be
determined. If you will not be doing your own finish work, you MUST
identify multiple vendors who can work with your timelines to create
repeatable finishes so that there is no differentiation in final
product. Define expectations and keep custom finishes for custom
bikes...you need known qualities and costs for this endeavour.<br />
<br />
Set a finished price for each frame that positions your product
competitively AND meets your business plan profit goals. These can
afford to be cheaper than custom one off work as you are batch building,
but that does not mean you are self depreciating the value or quality.
Set a defined profit that allows prosperity. If you are looking to
undercut existing product lines, you are doing this for the wrong
reasons. Predictable margins and productivity are your goals, this
should be a daily bread product. <br />
<br />
Network with shops that wish to represent or carry your brand and have
dealer agreements ready to be signed that clearly communicate minimum
orders, cost, terms, and parameters of product representation through
the build. Folks have stated various opinions on if you should provide a
discount/wholesale pricing model. We operated on a 20% margin,
offering shops the frame at our set price based on the previously
mentioned business plan targets. If a frame was sold direct, it was at
that same retail number, preserving equity in the retail market. This
gave the shop an easy bump for stocking a frame, but allowed them the
opportunity for greater profit if they built a complete bike.<br />
<br />
It has been mentioned that you should only sell complete bikes as it
maximizes your profit potential. For a small manufacturer, it is not as
easy as it sounds. It does take an inordinate amount of time to spec
and order OEM complete builds, assemble, and then pack for delivery. We
found that although we could make more money on the build, it did not
offset the time required for so few hands...the time was better spent
making OUR product. I would suggest creating component spec standards
for each model that maintains consistency for your bikes. Upgrades are
encouraged, but diluting your vision can not be accepted. Allow the shop
to build the bikes, the margin on the components and labor is another
share of the pie that benefits them and puts some skin into the
relationship. Their advantage is that customers cans see/feel/compare
the bike at hand and have it NOW vs. ordering directly from you and
waiting for shipping. Prices should be equitable, so that does not
factor into the decision making process for the customer. <br />
<br />
If you can sell a complete bike direct, do it. However, as a small
manufacturer, understand that you can quickly turn inventory over in
frame only sales. Your business is maximized by inventory rotation and
recouping investment dollars so that you have greater liquid assets on
hand. Many customers enjoy the process of completing the build own
their own, don't negate your product from consideration by only selling
complete in this small production plan.<br />
<br />
Ensure warranty standards are clearly defined and begin at the point of
sale. Handle them swiftly and accommodate a line item into your COGS
for future warranty work. Not every product will require it, but every
product sold should share the potential cost.<br />
<br />
Support the customer's desire to rep your brand with accessory soft
goods...have tees, stickers, hats etc available for stocking shops and
direct ordering. You are creating a brand and want to encourage
loyalty. Happy customers will be your best salesmen.<br />
<br />
Remember, this is a totally different plan than being a "custom" builder
and should be approached differently. Although the two can operate
synchronously, they are exclusive in operation.

One particular fork company has a 15 mm through axle that uses a different size male thread than everybody else on the market. I can hypothesize that the desire to have a "proprietary" design allows them to charge customers a whopping 90 bucks to replace it if lost or damaged. </span><span style="background-color: white; color: #141823; line-height: 19.3199996948242px;"> </span><span style="background-color: white; color: #141823; line-height: 19.3199996948242px;">So, reason #122 to own a lathe; make a custom insert to fit the more common 15 mm standard through axle.</span></span><br />

No, you can do much with hand files, patience, and skill. However, when a level of repeatable accuracy is required, the use of machines and fixtures arguably becomes necessary.

Seemed fairly straight forward and did not require a bunch of explanation if you are aware of the fundamentals of machining.<br />
<br />
When moving to titanium, it is a whole separate ball of wax, full of missteps and broken tools if you are not keenly aware of the changes necessary. As I'm just finishing up some titanium hot rod parts, I thought I'd share a few of the lessons that are worth knowing.<br />
<br />
<b><u>Know your material: </u></b><br />
<br />
When speaking of Titanium, we might as well talk about the grand daddy of toughness, 6/4 ELI in a non-annealed state. Machining titanium is much more difficult than steel, as the material does not like to dissipate heat, instead keeping it fairly localized. This means that you need to be aware of your tool speeds, feed rates, and coolant application to prevent tool failure and work hardening. If you push the material too hard, you will find your tools quickly dulling or becoming burnished at the cutting edge, the material pushing and forming instead of cutting cleanly, and an inordinate amount of smoke coming from your work space...not good in any combination.<br />
<br />
Ti also has an inherent springiness, a by product of it's elasticity. This makes it want to close in on your tool, so having a proper lubricant that reduces the cutting edge friction is paramount.<br />
<br />
<b><u>Know your process:</u></b><br />
<br />
Tapping titanium is not difficult, per se, it just requires a different approach. <br />
<br />
Preparing the hole for tapping will require a stepped approach, using more incremental sizes and a higher peck rate to insure that the heat build up is reduced. In the case of the spider interface below, I begin with a center drill to create a focal point, then use two drill bits to step up the through hole size, finishing with a third drill bit designed to work specifically with the tap I'll be using. Due to the hardness of the material, the final bit is one size larger than you will typically find on the suggested drill charts, as the 6/4 Ti does not need near the depth of thread steel or aluminum would require to for the threads to have sufficient pull retention properties.<br />
<br />
The extra steps and measured pace in creating the through hole is worth the time as it increases the longevity of the tap.<br />
<br />
<b><u>Know your tool:</u></b><br />
<br />
I mentioned that titanium does not dissipate heat well, keeping it localized during the machining process. This manifests in a binding action on the cutting edges of the tap, creating a circumstance where the force required to continue to advance will quickly yield to the torsional forces, breaking the tool off in your work. We need to select a tap profile that will limit that potential.<br />
<br />
The best choice for machine tapping titanium through holes is to use a two flute spiral point tap with a relieved back edge and tooth chamfer. This allows maximum space behind the cutting edge for chips to be pushed out the bottom of the hole while reducing friction and heat build up on the cutting surface. Several manufacture's make taps for exotic/hard metals, but I like OSG (EXO TI) and Emuge (Rekord C Ti) the best as they are material specific for titanium, have a nice tooth rake, and are designed for rigid tapping. Below is an example of some new bits and taps from OSG...I always start with fresh tools when I begin a run of Ti parts so that it is a pleasant experience. <br />

<a href="http://4.bp.blogspot.com/-W4IhbzENPCU/VNJ1_46qbCI/AAAAAAAAHbQ/PwP5fUxYdaQ/s1600/IMG_0078.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-W4IhbzENPCU/VNJ1_46qbCI/AAAAAAAAHbQ/PwP5fUxYdaQ/s1600/IMG_0078.JPG" height="320" width="240" /></a></div>
<br />
These taps are designed to be machine fed in one push...no back and forth hand work here, don't even try. The parts MUST be rigidly fixtured as vibration is one of the forces of evil to tap longevity. Make sure that you consult the manufacturers guidelines for speeds as they will differ. I run these taps at between 10-13 sfpm, That equates to an rpm around 240...seems pretty damn fast for how hard a material 6/4 is but that is what is required for proper thread shape and chip evacuation.<br />
<br />
You'll see that I am still power tapping with the mill, I don't use a tapping head. The key to doing this successfully is to only tighten the chuck enough that the tap will self feed but if it binds, will slip in the chuck before breaking. It takes a bit to get the right feel, but it is a process that allows you to start with light pressure and work your way up.<br />
<br />

<br />
<br />
<b><u>Know your friends:</u></b><br />
<br />
One of the best friends you have in tapping titanium is a little bottle of Moly Dee CF Tapping Fluid. Heavier and more clingy than your typical "Tap Magic" or equivalent, this lubricant will make life a LOT easier for you. Good friends do come with a price...expect to pay around 50 bucks for a bottle.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://3.bp.blogspot.com/-Qnfp01O6YEE/VNJ0VW-eIqI/AAAAAAAAHa0/PO0okHgyEOM/s1600/IMG_0028.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-Qnfp01O6YEE/VNJ0VW-eIqI/AAAAAAAAHa0/PO0okHgyEOM/s1600/IMG_0028.JPG" height="320" width="240" /></a></div>
<br />
Using these processes on my manual mill, I am able to get about 30-40 holes out of a tap before it is no longer sharp enough to cut efficiently, that's 10 crank arms. At a cost of $50 per tap, you can begin to see why working with ti can be such an expensive proposition.<br />
<br />
<br />
<b><u>Know what to do when things go wrong:</u></b><br />
<br />
Unfortunately, if you are going to be tapping a lot of holes in titanium, you will break a tap off in the work piece. When that happens, those buggers are STUCK. No amount of trying to turn it out using the brittle shards left above the work piece or breaking the tap with a punch will get them out. So what do you do?<br />

<br />
Drop the piece in a small container of Ferric Acid and walk away for a few days. This can commonly be found at Radio Shack labeled as a PCB Board etcher.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://2.bp.blogspot.com/-vo980CZkp9g/VNJ0EjeDAwI/AAAAAAAAHac/Wzn0M2HlU2w/s1600/IMG_0025.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://2.bp.blogspot.com/-vo980CZkp9g/VNJ0EjeDAwI/AAAAAAAAHac/Wzn0M2HlU2w/s1600/IMG_0025.JPG" height="320" width="240" /></a></div>
<br />
The acid will eat away at the cutting edges and thinner portions of the tap, leaving the titanium alone. After a few days, rinse it good and give it a tiny little tap with the punch, out it comes with little more effort than the patience to wait.<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
If you are going to make custom Ti bikes, you need to know how to work with all the variables of the material. I hope this gives a little insight and saves you a bit of time and money in the process.<br />

The North American Hand built bicycle show is a concept that
teems with potential and opportunity for the small independent frame builder. Never before has there been a vehicle that
affords the prospect of global awareness for hand built brands, creating
prospective customers outside the normally regional appeal our industry tends
to propagate. </div>
<div class="MsoNormal">
<o:p></o:p></div>
<div class="MsoNormal">
During its tenure, the show has evolved from a small
gathering of fabricators and key suppliers to an assemblage of creative
companies, representing a broad view of the cycling industry. Though some have argued that the show has
lost its focus on the hand built bicycle as it has grown, the key platform and
interest for the individual fabricator has remained steadfast; <o:p></o:p></div>
<div class="MsoListParagraphCxSpFirst" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> </span></div>
<div class="MsoListParagraphCxSpFirst" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<span style="font-size: 7pt; font-stretch: normal;"></span><!--[endif]-->- - a venue that allows for direct interaction with
potential customers, facilitating the start of a business relationship in areas
outside the business’s normal geographic reach<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Media exposure that bolsters builder recognition
and broadens awareness of hand built bikes<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Creates opportunities for builders and their
vendors for face to face communication, development of product ideas,
streamlining supply options<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Integrates ancillary cycling products into the
show, drawing cycling enthusiasts, increases potential reach and exposure for
exhibitors.<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Provides for an instructional medium within the
seminar framework, encouraging mentorship.<o:p></o:p></div>
<div class="MsoListParagraphCxSpLast" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Creates a physical sense of community amongst
builders who typically labor in solitude. </div>
<div class="MsoListParagraphCxSpLast" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<br /></div>
<div class="MsoListParagraphCxSpLast" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
It is with these benefits foremost
in mind that I feel supporting the show by consistent attendance should be a
priority in each builders business plan.
Fabricators working at capacity will not realize a Return on Investment
for participation that is tangible.
However, their participation does keep the industry in the eye of the
customer, provides a vehicle for new builders to find an audience, and invests
in the industry that has provided a living wage throughout a career. The show benefits all who engage in the
custom bicycle industry whether they attend or not, is there not a
responsibility to give back?</div>
<div class="MsoListParagraphCxSpLast" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<br /></div>
<div class="MsoNormal">
Much debate has transpired within the small hand built
community regarding the direction and administration of the show by its
Director/Owner, Don Walker. As a
business owner who is engaging in a relationship with Nahbs, I feel it is
important to recognize that in this circumstance, I am not only a customer, but
have an invested interest in the success and longevity of the show. To insure it’s opportunities continue to be
available to industry members, it is my responsibility to give feedback to
create an ever improving environment for positive change. For Nahbs to evolve as the leading marketing
medium for the small fabricator, I would recommend;<o:p></o:p></div>
<div class="MsoListParagraphCxSpFirst" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> </span></div>
<div class="MsoListParagraphCxSpFirst" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[endif]--> - A renewed focus on Customer Service to builders
that facilitates a sense of ownership/importance of Nahbs in their business
plan. <o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Affordability – Nahbs needs to establish a
financial model that enables attendance for its diverse range of exhibitors as
well as to provide a fiscal foundation for future existence. Tiered pricing that supports the independent
fabricator, as they are the focus of the show, facilitates annual attendance
due to consistent cost expectations.<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Focus on the hand built fabricator by
centralizing their booth spaces to support each other. Surround the builders by their supply
partners, offering consumers a direct visual correlation of the goods that go
into the finished product. Ring the
event by ancillary vendors that bring the fun and accessories of every day
cycling to the marketing mix.<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Professional development – many who attend the
show have an interest in someday entering the industry, it should be a goal of
this gathering to provide educational awareness and mentorship opportunities.<o:p></o:p></div>
<div class="MsoListParagraphCxSpMiddle" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Equitable show location choices in top tier
cities, throughout the United States, proportionally locating between the
coasts and middle so no one has to travel across the country more than 2 years
in a row. Travel and logistics are the
largest portion of show participation costs, reduce the financial strain by
insuring equality in location choices.<o:p></o:p></div>
<div class="MsoListParagraphCxSpLast" style="mso-list: l0 level1 lfo1; text-indent: -.25in;">
<!--[if !supportLists]-->-<span style="font-size: 7pt; font-stretch: normal;"> - </span><!--[endif]-->Discontinue the Awards structure…encourage
builders to bring product that represents the typical work from their shop and
allow the crowds to provide affirmation through their ultimate choice in who
they wish to work with.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
And as a personal note to Don…the strength of a man’s
character is often defined by his ability to let go of past transgressions and
accept people as they are, celebrating their strengths and supporting them when
they are in need. You have assumed the
mantel of an advocate for the custom bicycle fabricator, and subsequently, a
responsibility to lead. Do so with
honesty and respect for those you serve, and they will return it in kind. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In its short life, Nahbs has been responsible for launching
many new careers, fortifying existing business success, and bringing a global
awareness and recognition to the hand built industry. I have been pleased to be part of that
success and choose to continue to support the opportunities it presents.<o:p></o:p></div>

<br />
<br />
Here's the skinny on cranks for this year. I will be offering cranks in steel or titanium, lengths of 170mm - 190mm, with a four arm 104/74 spider or custom chain wheel configuration, for 68-73 width bottom brackets, in graphite black ceramic finish. If other options become available during the year, I will advise of such, but for now, that is where we are at.<br />
<br />
There will no longer be any wholesale discounts available. Fewer units mean I need to maintain my margin to keep the lights on and the kid’s college tuition paid. Sorry.<br />
<br />
I will be producing cranks three times this year.<br />
<br />
As we are taking orders for the entirety of 2015, the spots will fill based on first come, first served, the first months run is already filled with previous orders. To secure a place in line, please send a $50 non-refundable deposit by Paypal to rody@groovycycleworks.com. Please note in the comments box the material (steel or Ti), length desired, and if you need a spider. Please insure your shipping address is correctly noted on your account. We will acknowledge your order and advise what month the cranks will ship as well as the final amount due when your item is ready. Not sure you want to commit without knowing your production date…drop me an email and we’ll let you know where we are at.<br />
<br />
Thanks,<br />
