Embarrassing When You Forget A Skill
I was trying to square the end of a Delrin cylinder, and I can no longer do it! I started the cylinder spinning, and then tried to run the cutting tool across the end. At first, I blamed the tool not being shasrp enough, so I put in a new carbide-tipped tool. Same problem: part way through the tip would grab the material and pull it out of the 3-jaw chuck. Even using a dial micrometer to get the cylinder as close to square as I could did not help. Is there something I have forgotten?
