I had intended on trying the next speed up, which is 500+ RPMs, but didn't realize I had set the lever for double that. I ran a pass and it was slightly better but not much. Then I found part of my problem was I had one of the feed gear levers in the wrong position. I thought it was feeding much too fast from what I'm used to. Anyway, I was running out of diameter to turn so I had to abort. Galling is the major problem with turning the stuff now. I think I'll tackle another piece of 4140 for practice on another day.
