A while ago I found a video from Mr Pete about making a speed nut for the Bridgeport. I thought it looked like a fun project, so I made one.
The knurl went off when the part pulled out of the collet a little. It was holding the smaller diameter, seems like that was a bad idea. Next time, knurl THEN cut off. I honestly forgot I wanted to knurl it.
I suspect that the indexing error was caused by me missing a hole or not locking for the cut. Either way, my own fault. I guess it's a half thou or so off. I don't expect it to be that accurate anyway, so I'll just deal with it. "character".
I do like the paint stick though. The marks are nice and easy to see. One of the many good things people here have convinced me to spend money on.
Overall, I'm pretty happy with the result. I also have the threaded piece and spring done and it moves over a 1/2-20 threaded rod nicely while holding well when released.
Now I have to take the mill apart to install it. That might happen soon, maybe.... Lol.
