I don't know exactly where to put this - I am chucking a 16" long 1" piece of high carbon steel, about 30RH. Am using a live center in the tailstock.
When trying to run a profile, I'm getting a good deal of chatter closer to the live center that tails off when you get closer to the chuck and the center itself. I get a hell of a snakeskin pattern on the workpiece.
Cutting tool is a CNMG 432 MM Sandvik insert, 730SFM, .01" feed .02" DOC.
Anyone have any advice?
