1940 Sidney Lathe Rehab

[FOMOGO]

20ton air over hyd. Actually came off without any drama.

Wow, I would bet $$’ to donuts that bearing wouldn’t have come off the shaft, or you just have a really big press

Had a similar but not as bad problem with my Hardinge. Think the carriage was bumped with a forklift and damaged some teeth on the pinion that engages the carriage rack.
It has two gears on the shaft so replacing one made more sense.


I machined the old one away


Then cut a new one and shrunk it onto the shaft

In your case I think I'd make the whole thing. Cut the new gear on a new one piece shaft.

This one is one piece, and is the gear that engages the rack for the carriage. The rack seems to be fine. I think this one suffered the same kind of damage that yours did (death by forklift), as the cast guide for the taper attachment has been broken and brazed up also. I've pretty much come to the same conclusion on making a new one. We will see if the trusty Atlas is up to the task. The R8 arbor, and gear cutters have arrived, and will cut the gear on the BP, so just a matter of getting to it. Thanks for the replies. Mike
