Tidbits of the week...

How long does a diamond wheel last when sharpening thousands of tungsten?  About 15 years I guess...the new wheel from Norton, ready to install .


A bucket full of LUV centers for the next months batch, cut, faced, deburred, polished, and bent...


Machining a window in a headtube for internal cable routing...


A look from the inside, the insert sits flush with the inner wall of the 44 id head tube...



A beautiful sunrise to walk to work under, a benefit of having the shop 100 yards from my back door...


The Mad Weeder prowling the neighborhood looking for vinyl mask to separate... 


Working on pulling out the fine details of a down tube mask...


The mask and transfer sheet applied to the ti frame, getting ready for the blast cabinet...


After blasting with a 120 grit...


The image with the masking removed... 


The final product...

That cable feedthrough looks like a though one to weld cleanly…

What kind of settings do you use for welding thin steel tubes?

Does the hollow grind created by grinding on the diameter vs the side affect torch performance?

Drew,

The diamond wheel is a 100grit Norton. Grinding on the side of the wheel will create circular lateral paths that will cause arc wander...always want to grind parallel with the length of the tungsten. I load the tungsten in a cordless drill on slow speed and use a steady rest to allow me to create a long taper.

Allard, I guess I'm too old school for "settings", all my steel welding is just straight amperage with foot pedal control, no pulse, ramp up, etc...
