Detroit bound today

Hey y'all, quick post cause I'm bushed...

Drove up to Detroit today with Mike S to pick up the Lagun FTV-2 from Tartan American Machinery. I headed up with a bit of trepidation, as I had tried a couple of times to get the pick up date scheduled and was advised the mill was not yet ready to go.

Those worries fell away when I arrived; Tim (pictured below) is the go to guy at Tartan for machinery repair and prep. Tim had lovingly worked on rebuilding this machine for the last year from the ground up, insuring that each part was as perfect as it could be. His desire to send out the mill in A-1 shape was responsible for the delay and his goal was realized...Tim, you did a bang up job! I'll proudly take care of her for years to come.

I've gotta give major props to the folks at Tartan, from the excellent communication that Chris provided to the preparation prior to delivery by Tim, each step was handled in a professional, friendly manner. You could not do better than to work with this fine group...check them out if you need some new toys in the shop... click here

Gonna move some machines around in the am to fit the Lagun in and will be working on catching up on email in the afternoon between paint work. Thanks for everyones patience.

Not feeling on my game today. Probably a combination of... uhh, who knows what, just didn't have it.

I worked through the vintage dropouts and fork crowns today, checking the spec and getting them ready to use on Steven's build. I'm pleased with how they came out. I need to do some final machine work on them; breaking the edges, tapping the M10 derailleur threads, cutting off the material anchor holes.

With the dropouts in hand, I set to working on developing a system for bending the stays for the project. I knew this was gonna be a bugger to get right, here's why. Most Klunker style seat stays were one of two types; either they were long stays that ran from the dropout all the way to the headtube with just a single bend to meet the seat tube, or they arched up to meet a segmented joint at the seat tube. Modern adaptations have used "tee" joints to meet the seat tube or a monostay and "tee" joint to fit the rear end together. Steven wants something that looks fluid, so I played around with some options. In the end, I decided the most aesthetic and functional design would be to use a single stay with a compound bend...rolled for the constant radius into a single lateral bend to meet the seat tube. While this will look the best and offer the strongest joint, it is also very difficult to achieve.

I spent the afternoon experimenting, working on a process to get both the lateral bend and the rolled radius without crimping any of the bends. I finally hit on a process that worked well and am moderately happy with the first stays. I'm gonna fine tune the dies a bit more and then make Steven's pair.

Here's a couple shots from today...

Making a new bending die to fit the 1.25 pivot post...
A top view of the seat stays with the lateral bend...these will yield 3 inches of rear tire space.
A side view of the mock stays in the fixture. I had to really arc these more than I had planned due to the short span from the dropout to the seat tube for a visual radius to be present. This is the bend I want to fine tune a bit before I make the final pieces.
I'm looking forward to doing up the plate fork crowns, I think they will compliment the style of the dropouts and really bring the bike together in a balanced look.

cheers,

Friday's Hot...in the shop and on the job

Hey y'all,

As I finished up email Thursday night, I glanced at the clock with drooping eyelids... "0100 hours, gonna be a short night".

Seems like the alarm went off at 0430 as soon as I closed my eyes, but I needed to get a couple of hours in at the shop before heading to the fire department for a shift. I'm actually pretty productive in the early hours; the phone doesn't ring, no one stops by, and there's nothing to see out the window so daydreaming is kept to a minimum :)

I started stripping off the decals on Jim's Fox fork that is to be painted in a Jolly Rancher scheme to match his Bigwheel. Who'd thunk it would take over an hour to pull off some decals and their residual stickiness. Let me tell you, if you are getting an new 2010 Fox product, the decals are gonna stick in there for the life of the product ;)

An X-acto knife, weeding tweezers, and a lot of Goo-be-gone and elbow grease finally left me with a pile of scraps...
With the decals all gone, a quick mechanical breakdown, solvent wash and some 600 grit paper will get these babies ready to head to the booth. Yep, that's right, I do not strip off the powder on the forks before painting. Here's the reason why. The magnesium legs that are common castings on fork lowers have a physical property of "off gassing", where the material constantly emits a gas. To paint these, you need to use a specially formulated primer that creates a vapor proof barrier. If you do not, a liquid paint job will develop a bubbled type of appearance rather than laying smooth. Powder coats will tend to have a shadowing effect, being darker in some areas than others. As Fox already has a non-permeable base down, I'll simply mechanically and chemically prep and build off of it. The tolerances are such that I can keep the layers thin to avoid any post paint interference.
Once I got Jim's fork on the way, I started to blast a few rigid forks to be sprayed up this week...Dario, Michael, and Miguel, these three are yours and the last that I am doing until I can get the build list caught up.
Satisfied with some work completed to set me up for next week, off to the FD I went, arriving at 0630. I had just met with the other shift commander and began to accept the command for the day when the alarm sounded for a garage fire. We stopped, looked at each other, and both decided to go. The benefit for me is that my typical position requires me to organize the fire scene from the exterior at the command vehicle. With another Command officer on scene, I got to revert to my true love, playing inside the fire.

There is no high attainable that can compare to an interior attack on a structure fire. The feeling of crawling into a dark structure full of adrenaline, incredible heat pushing you to the floor, every instinct in your body telling you this is wrong, but pushing forward regardless. Soon the very air around you is dancing with tendrils of light and flame, rolling over your head as it crosses the ceiling and licking ever closer to you, eagerly consuming every material in the room. It's then that you are in the zone. It's almost magical to watch, intoxicating with the flood of endorphins, and seems a shame to open the nozzle until reality hits you in the face and you realize, Damn, it's fucking hot in here! Within seconds of adding water to the mix, the room falls pitch black, the heat changes to a severe suppressive force, full of moisture and steam, and your focus changes to quickly getting some ventilation to reduce the temp and pressure... too cool.

I was fortunate enough to play at the garage fire which flashed on us, but then luck was on my side when less than a minute after going available, we were sent to a house fire just a few streets over. In the front door with the line to do it all over again, oh yeah!

Here's a shot of the house just after knocking the fire down courtesy of the local paper...me and the rest of my kick ass C shift crew are somewhere on the second floor right now...

As much fun as it is playing on the inside, the downside is the rest of the work. Salvage and overhaul, investigating, clean up of the equipment and then hours of paperwork. The crew and I finally finished up with everything about 1830 hours, 12 hours after I came in. Breakfast and lunch had passed us by and the day was not yet half over but I was shot. Being a Friday night with warm weather in a college town, the prospects of getting much rest were not looking good.

Needless to say, I was pretty worthless in the shop yesterday. Christi was out of town for the day so I ran kids to ice skating and swim team practices, prepped a few more bars for shipping, then took the afternoon off to run the dogs at the knob and do a bit of street luge with Kalten, Emmy, and our friend Tim Long on Flickenger Hill; a nice long straight run that gets you up to about 30-35mph, a good rate when you are an inch and a half off the ground.

Gonna hit email today and see if I can get some more web page revisions done. Oh, also got two sets of the vintage dropouts completed, so I'll be finishing Steven's project this week, finally!

cheers,

rody

November contest answer...oooh look!

Guys and gals, I really enjoyed reading your responses guessing what in the world that little fixture could be for...you really are a sophisticated group :)

Alas, Sean of Vertigo Cycles, www.vertigocycles.com , shared the correct answer, although I think he may have had some inside experience ;)

Welding titanium is a finicky process that requires a couple things;

1.) a totally anal retentive approach to material prep and cleanliness
2.) an oxygen free environment until the material cools below 800 degrees F
3.) a methodical welding process to protect against the materials desire to pull and move
4.) patience

The fixture helps me with #2. As you can see in the pic below, a titanium grip section with a breather hole 1.0" from the end is inserted into the tight tolerance section of the fixture. The end is then plugged with the argon feed and argon will then fill the larger chamber through the breather hole. The slotted window allows me to drop in an end cap, push the grip section up tight, then weld it in place while bathed in an oxygen free environment. The flat stock orients the fixture on my roller so that I can still spin the grip section for fusing the end cap...silly fun!

When there is contamination...either oxygen, dirt, or otherwise, you will get a very pretty rainbow of purple and blue color; pretty now, doomed for failure later. You want a totally shiny finish when you are done. Here's the first piece out of the fixture...

Overall, I'm really please with how it came out.
Now, there were lots of super answers, but only one correct one. As Sean already has a shirt and stickers, I'm going to honor his request and pass on the bounty to Grumpy as he was first in with a more descriptive answer (Roy, you were in ballpark, but honesty, don't you teach kids? What kinda run on sentence was that? ...read with heavy sarcasm). So Grumpyone, email me and we'll get some stuff out to ya.
As a round up for the last two days...I powdered all the steel bars and finished fabrication on the Ti's this afternoon. Christi took a car full of packages to the post office and we have about 10 bars that we could not fit in to send tomorrow. So, if y'all are expecting a Luv, it should be coming soon.
cheers,
rody

November Contest Madness...

Hey there tech heads...I assume that most of you follow the blog because you enjoy seeing the build process unfold in front of your eyes. Well, as most of you can bear witness, it takes a variety of tools to accomplish the fabrication process of a high end bicycle in an efficient and consistent manner.

Today, I added another piece of tooling that cuts down on my fabrication time and increases the quality of my product. It's something I've needed for a while but just have not taken the time to make; today was the day.

So, let's see how intuitive y'all are. The first one to post a comment that correctly describes the intent of this item and how it works will win a free Groovy Tee and sticker, mailed to your door. Of course, you gotta be a registered reader/follower to play :)

Here we go...

The first pic shows the ingredients for the item, can you visualize what it is to become?

Some quick fabrication time elapsed and we have the finished product...a view from the side
from the top, note the lateral slot and the small nub on the inside end.

Bottoms up... an enclosed end cap and a mitered plate to note in this shot. The other end of the tube is open.
I'll use this little guy every month, so those of you that are familiar with what goes on in the shop will have a head start. Have fun, we'll do the big reveal later tonight :)
Good luck,
rody
PS...Hubby, you don't get to play as you heard about it on the phone last night ;)

Saturday summary...

Quick post folks, this is the schnizzle, fo shizzel!

Working on lots of bars, both steel and Ti...
Ever wonder what 350 dollars worth of bubble wrap looks like? This stuff goes quick when you are sending out bars, forks, and frames... doing my part to stimulate the economy.
The parting shot...as I was leaving I had left the blast cabinet light on and it was illuminating the old neon Hardcore quite nicely. Gotta love the 80's!
Having a slow day at the Fire department, so I was pleased that I could spend some time updating the website. New pics, new colors, a new vid page, and I'm working on modifying the Gallery page with slide shows instead of random pics. There will be some more changes in the near future as I remove some pages to re-direct the business model to focus on more frame work and less small parts. I'd like to add a Customer bike's page and some feedback/testimonials, both good and bad...tell it like it is. Check it out and let me know where you'd like to see it go. www.groovycycleworks.com
Welding Ti tomorrow, hoping to pick up the dropouts and fork crowns too. Tuesday I'm on the road to pick up the new mill. Wednesday will be working on Steve's rear triangle and paint on bars, forks, and some powder work.
cheers,
rody
