I had this pressure knurling tool that came with my PM lathe that I would not dream of using due to all of the comments on spindle bearing pressure. So I hacked it into what I really needed - a tool post indicator.
I was sitting there afterward with a pair knurling nuts in my hand and when I remembered Shelly's knurling tool post, so I got work. This one is a lot uglier but it seems to work good. I tested it in 4130. The body is 1018 and the knob and screw are 4130.
The spring is it a little ugly but after a few attempts I got it sized such that the tool will close to zero and open to it's maximum 2" knurling size.
This my most "complex" project to date and I learned a lot.
