Making custom driveshafts

[Lizooki]

I know I'm a little late to the party but we would use the heat and quench method to straighten steel axle tubes. So it works.
Like someone said get it red hot and drop a wet rag on it ... add more until it cools to the touch.
But .001 on a driveshaft would be vibration free on a lathe spinning wide open.

My method of welding: one good tack, rotate and check with the dial indicator. Whack it at 180* to equal the first tack the tack it. Rotate and repeat until you have 4 tacks at 90*.
Burn her in. Never had one move.

Exactly the methodology used

Your work and attention to detail is amazing as always! And I’m sure slightly more accurate than the method I used to build mine.
