I did a bit of repititious work a while back that required parting off to a fairly precise length so I decided to make a sturdy adjustable stop. I wanted to make it where it could handle fairly long work so decided against the typical bicycle gooseneck style clamp arrangement and the tapered pipe thread expanding type slipped at the wrong time on the other lathe.
I picked up a 9x20 preload spanner nut from Grizzly to screw onto the extra available threads on my 8x18's spindle and attached a chunk of 2024 onto it. I wanted the stop shaft hole to be concentric with the spindle center so I made an extension drill from 1/2" shafting and drilled the stop using the tailstock to hold it and a piece of 1/2" ID brass tubing in an ER32 collet to center it. I then turned an acetal bushing that fit the spindle bore closely to reduce drill wandering. It works pretty well.
