Prompted by Philip Stevens quest for knurled nuts I had a look at the collection of lathe tools i inherited and found that i do in fact have a small two wheel knurling tool (not the clamp or scissor type just the simple one that you push up against the work)
I have no idea about using it though. What speed to you run the lathe? very slow with the back-gearing in use or faster?
