I turn mine much like Dennis. The slowest speed on my drill press is 470 rpm and seems about right. It is very important that you lube the case neck inside and out. I use PG2000 and dip the neck in a very shallow puddle before each case is turned. Feed on and off at a rate that eliminates the "threading" mentioned above. Be aware that feeding too slow burns off the lube, galls the neck and raises temperatures considerably. Once you get the hang of it you'll have a consistently warm (but not hot) mandrel and cutter all the way through a large batch of cases.
