My Chinese 13x40 has a threaded hole coming up from the bottom of the tail stock casting and a hardened pin that fits the slot in the quill and is threaded at the bottom. It has a screwdriver slot for adjusting it. The pin is screwed in from the bottom until it bottoms out in the quill key slot, backed off just until it will slide freely the entire travel of the quill, and then a lock nut is tightened to the pin to hold the setting. It is a poor design. Its only redeeming quality is that it will probably fail before something more expensive does.
