Have you tried pressing out the pins yet to replace the knurl wheels? I'm curious how easy/difficult that is.
Re making a clone. I have this Eagle Rock scissor type knurler. It works pretty well, but I find removing the pins to replace wheels to be a royal pain. They are a real tight interference fit. I dont have a press, but I think thats whats required. After some hard whacks with a punch, I concluded it wasnt going anywhere... so thus far, all my knurls have the same pattern
Once upon a time I drew up a dedicated mini-screw jack tool that might do the trick, but have not gotten around to it yet.
Anyway, if I ever make a new knurling tool, I would use shoulder bolts (I think thats what they are called). The ones with hardend & ground shaft part but threaded on the end so they can just be unscrewed.
