|Scott's Craftsman 101.07403 12x36" Lathe, modifications and projects.||Unique Visitors:|
Came complete with stand, a complete set of gears, a milling attachment, a Phase II QC tool post with 5 holders, steady rest, dozens of tool bits including a 5-piece set of indexable carbide cutters, 2 drill chucks, 5" self-centering 3-jaw chuck, 6" 4-jaw independent chuck, 4 centers, collette chuck, ball-turning attachment, parts list, and Atlas Lathe Operations Manual.
Have spent weeks rummaging through the box of tooling. Some stuff I'll never figure out what it was for.
Everything works. There is some slap in the spindle pulley, new bearings are on order. The counter shaft has a bit of wobble. Should be an easy fix with a new shaft.
I have cleaned it up a bit. All the Gibbs and bearings needed adjustment. I turned a new counter shaft as I did not have any 0.75" stock. That got rid of some of the wobble. The motor was shot with a bent shaft and decaying cloth-covered wires. I replaced it with a 3-phase motor and used a Variable Frequency Drive (see menu at top.) Now it is real smooth and quiet.
The counter shaft main pulley was way out of balance and wobbled. I had to bore it, re-sleeve and do all kinds of machining to get it near straight. See the Zamak Pulley Fix under Projects.
Have now fitted new spindle pulley bearings. Now runs nice and quiet with the back gear.
When I got it, it shook, rattled and made all kinds of noises. Now it is near silent and smooth.
I have a pdf copy of the parts list for the lathe here.
Here is an updated thread table. It is for an Atlas 10" but is the same.
