Working on a Sherline 2000 mill with Sherline's vise: I've indicated vise and it is as close to square as i can measure. I'm trying to square up small pieces of 1/4 X 1 hot-rolled, which of course starts out with crowned surfaces and pretty rough. My first cut is to clean up one edge. I then turn piece over in vise and clean up other edge, which I would assume would produce parallel edges, but for some reason doesn't - about .002 off in an inch of length.
My thought was that if i can't get two faces parallel it is never going to get better. It seems possible that the crown on the one inch wide surface is somehow causing the piece to lift in the vise when I tighten it up. It occurs to me that maybe I should put something on the slide face that's softer to better grab the piece and force it against the stationary face.
Maybe the question would better be how to get a reliable grip on rough stock.
