I've got a 101.28990 lathe. The PO added a QCGB and a VFD controlled 3-phase motor. But he still had the original spindle chart that came with the lathe, and it is in pretty good shape. Better shape than I'm in, and just as old.

I know some of you guys are into restoration, and you're welcome to it. I'll drop it into an envelope and mail it off to the first reply I get that has an address.

Good point Braeden. PM if you don't want to advertise your address.

Another point - the 101.28990 always came with a QCGB. What "spindle chart" are you referring to? Rather than spending a bunch of time trying to describe it, best way to answer would be to post a photo of it.

The Spindle Speed Chart. I made an assumption that would be the name for it, but I don't mind being wrong so much.

I wish Atlas would’ve included this chart on my 10F. Same speeds. I have this info laminated and sitting on a bench near my lathe.

I know why they didn’t: besides the bed Atlas hardly left a single flat surface when designing my older model
I do like the design with more flat surfaces that you 12-inch guys have.

Nice of you to pass it along.

OK. That is the spindle speed or RPM chart for any of the 1/2" bed lathes built by Atlas and sold by Atlas, Atlas-Clausing, Clausing-Atlas, Clausing or Sears between 1957 and 1981. It mounts on the flat front of the headstock casting in between the back-gear engagement assembly and the tumbler, with the top about half an inch below the top of the headstock casting. There should be one on your 101,28990. If there isn't, then that one should be.

Also, the PO did not add a QCGB to your machine. It came with one already installed. It also came with the much stronger right leadscrew bearing support and with a slip clutch mounted on the gear box output shaft to limit damage caused by a crash. The manual that came with the lathe explains how to adjust it to one lb-ft of torque. However, there are only about three valid excuses for a crash: massive heart attack, massive stroke, or nearby detonation of a nuclear or thermonuclear weapon. Hopefully you will never have one.

I need to talk to my neighbor down the street, then. I'd hate for his hobby to cause my lathe to crash!

I would like to have this. Is it still available?

I also just picked up a 101.28990 Craftsman lathe and would like to find that same chart of spindle speeds. Does anyone know if those are available as a wall poster? I’m new to all this so any help is appreciated!
Thanks
