I’ve had that same problem with a Jet 1220 lathe. The clamp bolt stretches when you tighten down the tailstock. It’s a cheesy setup in my opinion. The bolt rides on a camshaft, when you rotate the handle the bolt gets pulled up against the bottom of the lathe bed to tighten it down.

This should be the part you need.

Part # 64 in this picture.

I had to replace the clamp nut also, # 81 in the picture, that’s right where it stretches. On mine, it’s a 3/4” bolt cut down to 3/8” and it’s too weak. I’ve replaced it twice already. It’s an easy fix. If you bought the lathe new, Jet warranty will cover it.
