I am building the hemingway straddle knurling tool. I have to make a decision on what size knurling wheels to use before I cut metal. It is designed for 1/2" dia x 3/16" wide x 1/4" hole dia. knurls. Can anyone ecommend a source for reasonable quakity knurls this size? Accutrak makes nice ones but they are $31us each. I'm sure if I was doing production work they would be worth it but I'm not. Any suggestions welcome.
