driveshaft angles
I have developed a system to cut and weld driveshafts without using a lathe. I have never had an imbalance problem or vibration from them. I've lost count of how many I've done. So, yeah, I'll comment based on what I know, not like some who comment based on what they think others know. I've studied pinion and yoke and driveshaft angles for years so that I could do my own work. If a competent shop had been available, then I wouldn't have had to learn this stuff, but after getting burned a few times you adapt.
