StanF South Bend 9A Rebuild Thread
I'd leave the TA off until needed. Yes, it will wear down the rear shears badly. I had a 9" years ago that had the TA on the lathe and yeah it wore out the shears on the underside of the saddle badly from all of the weight of the TA. Just my opinion.- 4GSR

Hendey taper problem
I did use the compound from a lathe to finish the taper to gage with a new endmill holder at the time on the mill I had at the time.- 4GSR

Hendey taper problem
Cut a National 40 taper in the spindle and move on. May not be able to put the driving keys on the face of the spindle and I wouldn't worry about it. I had a old No. 3 B & S horizontale mill I converted it to a National 40 taper. It was so much easier to get tooling for it rather than dealing...- 4GSR

Lathe Screw Threading Issue.
32-tooth is standard tooth count for use with a 8-pitch leadscrew. 24-tooth count is used on a 6-pitch leadscrew. This is for imperial pitches. I don't deal with metric or any other pitches where the tooth count may require 24-tooth gear. -

3D Printed Gears
True, these may be replacements to sell to others. I disagree about these being ESTY crap. All M.B. is trying to do is come up with a alternative method of manufacturing these that fit in with his business model without having to invest into specialize machines to cut gear teeth. M.B. is not...- 4GSR

How do you handle people touching your tools.
At my first job way back in time, the boss put me in the office to do his dirty work per say. Meantime they hired a machinist to take my place. Dude showed up for work that morning, had no tools. Shop manager came in and asked if I had a scale/rule he could use until he could get one. I had a... -
3D Printed Gears
Be a lot of work, maybe, to put either a spline or multiple number of keyways on the shaft and duplicate that to the gears. Another thought here. The key here is to distribute the loading across the full circurference of the shaft and gear and not just in one spot or keyway.- 4GSR
