ran the numbers thru the big chief tablet and they said to use 0.875 for the 20 pitch wheels I had so I turned the 1" hunk of O1 drill rod down to 0.876 and ran the knurler up it and then back down after re tightening the adjusters.
First pass
Second pass back over the first one after re tightening the adjusters I wasn't trying to get them needle sharp diamonds that will tear your finger prints off just a good grip.
there are a couple things I will change if I make another one like a bigger bore in it and larger slots for the knurl shanks, but it sure beats the hell out of the other one I have. And I had the right diameter of stock for the pitch rolls that I ordered which stops the running over.
Here's a link to a youtube video that I used to calculate the Diameter for the rolls that I have.
