thats kinda getting back to "getting away with it" no?

the tube end does need a nice straight cut to seat the yoke and help phase it I would think.



Nope, being square has nothing to do with phasing and the yoke doesn't need to be fully seated as long as the center-to-center distance is the same on both sides...a little gap will just be filled with weld anyway.

I have done numerous driveshafts at home, on some of them I bought brand new end yokes and drove them into tubing that had been squared off in my lathe and never had a problem. Later on I found that this doesn't quarantee centers are equidistant...using a vernier to check the center distance often leaves a slight gap on one side before welding.
