Atlas/Craftsman 618/101 lathe. Can I use an AXA tool post and other?

And do you have to clearance the round top of the compound so the tool post has clearance to rotate?

I did not. I ground a shallow relief off the two offending corners of the tool post instead. Works fine.

I have the same model lathe, just newer (S/N 953). Your QCTP should work although you will need an 1/8" shim washer under it in order to have 360º rotation. Some have modified the compound to get the clearance but I would not recommend that as it will weaken the already fragile compound.

Although you may be able to mount 1/2" tooling, I would advise against it. There is no benefit from the increased rigidity, the tooling cost more and in the case of HSS or brazed carbide tooling, it is more difficult to grind. The compound becomes the weak link and is more likely to break if you crash the lathe. In particular, parting on the 6x18 lathe has a tendency to be finicky because of the flexing.

I have had mine for over fifty years and mostly use either 1/4" or 3/8" brazed carbide. I also use HSS tool bits from 1/8" to 3/8"where I need a custom form. I regrind all my tool bits and for the carbide, I use a HF diamond disk mounted on a small motor.

Congratulations, looks like a good score.

Great score on that lathe!
Tho I love my Aloris, for a small lathe like that I would consider a 4 square type TP.
A 4 square isn't quite as handy as a QCTP but when you think about it, four different bits will do about 80% of the functions you will ever do on that lathe.
They are much cheaper too.

For the chuck key, try hardware stores or online; a 7/32" Allen key should work. The AXA tool post might be a bit tall for your lathe, but the one from Little Machine Shop is decent.

The Little Machine Shop OXA QCTP works very well on my Craftsman 101.07301badged Atlas 618. These small lathes are pretty incredible within their capacity once you have them in good order.
