That is my Plan B. Kind of hoped to sort out where the weak points of Plan A were and if there where a good fix.

Seems a similar alignment issue. Gear is just a bit too big for a 5C collet. Plus the collet would not likely provide the support for the thrust involved. It is an even number of teeth so a 3 jaw chuck will not engage the teeth all the way around. My 4 jaw Chuck are all independent so then I need to center. The way I center I guess I would need to turn down a rod snug to the bore and use a dial test indicator.

Any other ideas cause my press is looking good right now
