Tx Jim, I took your idea today and ran with it. I got a couple 1/4in grade 8 bolts like you said. I removed all of the insides of the shaft. I also am having a machinist make a spacer to replace the 1000 rpm gear. I forgot to pick up lock nuts so I will pick them up tomorrow. My question now is what do you mean by a welch plug?
Glad to be gaining ground on this thing!! Thanks Guys!!
