Please explain how Knurling works - cut matching

[gorlosky]

I see what bump and scissors straight and 30 degree angle knurlers are, in 1 -2 and 3 wheel setups. I see that many 2 wheelers have opposite cut angle wheels, so in eseence they are 1 wheelers, but with any of the 1-2-3 wheelers, how does that single pattern cut in and repeat itself ? Looking at gear teeth, they have to be calculated and made so that there are no half teeth, which knurling surely would create.

There's lots of great info in this ( http://www.hobby-machinist.com/showthread.php?t=20421&highlight=knurling ) thread, along with some knurl calculating tools. Happy reading.)

Keep in mind that you can use angled knurls to cut straight knurls too. Here is a quick tool I hacked together for a thumb screw project I was working on recently. You will notice that the knurl touches the work horizontally.

Good thinking. I have an idea to build a 4 wheel clamping unit that will do 1/2 inch to 5 inches. Stay tuned. Speed knurling.
