....continuing with my ramblings, I use the NWSL drive shaft parts on my diesel drives but rarely on steam. On the really heavy ones I have the plastic burned out and cast them in bronze. Obviously, it worked out for you. Having the gearbox and motor in, as close as possible to, perfect alignment is a biggy. Two thoughts though, I would lubricate the ball and socket. I've seen them wear out under heavy loads. I would also try to stabilize the gearbox to prevent what we used to call wrap up. When we use the longer shafting and rubber tubing we are mitigating this issue.
