Did you dynamically balance the d-shaft? I'll skip the back and forth and assume no... why not?
I cut the tube length on a lathe and I retrued up the yoke and spline as well on a lathe and made everything press fit so I am fairly confident it will run true enough for me. If I am wrong then I will take it in and have it balanced.
I have seen a friend cut tube with a saw zaw and then eye ball weld in a yoke and spline and the thing ran God willing true with no vibrations. So the fact that I took the time to true everything up and press fitted everything before welding I will be fine. I will find out Friday if I am wrong or not.
