Hi once again,
I bought a three in one push type knurling tool and soon discovered it was meant for larger lathes so made this using the wheels and pins.

When I accidently bought some straight knurls the wrong size figured out how to mount them without making another tool.

I've discovered that if you start a knurl and the pattern isn't even then by holding the bottom wheel with your finger, loosen clamp and just turn the top wheel a smidge fixes the alignment. Is this a common technique?
