QCTP knurling holder fix

...or you can replace the knurls with one bearing and make a bump tool.

Since I have too much knurls, made a comparator display to better (visually) choose the right one.

I found I had to put a spring between the two arms to keep the arms from collapsing, loosing adjustment.

I just came in from knurling a bunch of stuff with one of those things, because it's the only knurling setup I have at the moment, and found this thread. I'm putting this on my project list right away!

I don't know but i am kicking myself for not thinking about using a "Bump Tool" to align parts on the lathe! Thats definitely moved right to top of my "next to do list!"

Cool man. You took a tool and it much better. Great stuff.

The problem with my QCTP knurler was that the actual knurls didn't run concentric. I imagine that if I replaced them, the tool would be of some use. I made me a Marlco clone last year that works so well, I'll probably not bother to replace them. Here's a pick of my knurler:

I cut the knurling end off, extended the slot, drilled and tapped for set screws and mounted my (home-made) scissor type knurling tool there.
