Go to k&mshooting site. You will need an expander.They have kits.Ok I'm shooting a 22-243 and want to start neck turning. I'm looking at the km stuff. What do I all need. I see on midway they have the neck pilots and the turner with cutter and the case holder and handle. What esle do you all need?
Roughly what RPM are you using while advancing?The PMA tool power turning adapter is better than K&Ms. I have both. IMO when you are turning you should not try to hold the turner rigidly or for that matter the drill that is powering the case. Use low RPMs and go to the shoulder rapidly, leaving a rough cut, come back to the mouth very slowly, and do not go back. Finish by clamping (in your hand) a wad of 0000 steel wool around the neck and spinning the case (higher speed OK for this) for a second or so. While you are at it, if you have a trimmer that indexes off of case shoulders you can trim, chamfer and debur, before removing the case from the power adapter. If you are getting much heating your cases are too tight on the mandrel, you have a lube issue, and/or you are using too many RPMs. I check neck thickness for each case before turning the next one, with a neck mic, that reads to .0001.
I use the slow gear setting on my old Makita at part throttle. The reason for advancing (moving the cutter) to the shoulder quickly is to leave plenty to cut on the way back. By doing this the case neck is always cutting the whole time that it is on the neck, which keeps the neck firmly pinned to the mandrel. Doing this and letting the turner and case freely align to one another, letting them wobble as much as they "want" to improves runout. Doing it this way you can turn very good necks even though the fit to the mandrel is not as tight as some think they have to have.Roughly what RPM are you using while advancing?

Thanks. That's ~4 to 5 revs per second. FWIW (to no one in particular) if you count seconds like a young music student learning 16th notes "One-ee-and-ah, Two-ee-and-ah, Three-ee-and-ah ..." that's 240 rpm (4 revs per second.)RPM-
I try to keep it at 250-300. I would not bother with the small screwdriver type tools since there is not enough torque. To save you some time, try the DeWalt full sized drill.
Sure, I can control speed with finger, but not as precisely and easily as I'd like. Plus I'm trying to keep the finger pressure static while at the same time using the same hand to advance and retract the case. Probably would feel easier if I was 25 again.Brian-
I chose the DeWalt because it was the only one at HD, Lowes, Ace or Sears that I was able to keep that slow speed with just finger pressure on the trigger.
It says:For those of you still struggling with keeping your full size drills at slow speeds, not to mention holding unto that heavy thing for hours...

I bought mine at local Menard's , spent $8 on a 2-year extended / hassle free return warranty.. That was 4 years ago,,
I turn everything from 6mm to 50BMG with no problem, and this little guy is a hell of a lot more ergo,
I can turn about 20 50BMG cases on a single charge, ( So I bought extra battery) and anything smaller than that , it never runs out of juice.
.It says:
"21 clutch settings + 1 drill setting for precision and control based on the application"
Is the "1 drill setting" feature where the precise speed control comes in?
Edit: Oops, my bad. There is no trigger, it's a fixed-speed (or possibly discrete multi-speed) screwdriver of course. Sorry.

As long has cramming the trigger down produces a steady slow speed, that beats the DeWalt I use. But with battery power, speed usually drops as the battery wears down, unless it has a constant-speed circuit which means it will run 200 rpm while possible, then simply shut down and indicate "charge me!". (I doubt it, it will probably gradually slow down.).
Your right, just a fixed speed,, " Low" is 200rpm . .. It's easier to hold the trigger down, as it kind of is your natural grip anyway .. I know I hate turning necks, ESPECIALLY on the 50BMG,, so I look to make it as comfortable as possible

FWIW I have a Bosch Colt laminate trimmer (small router, A/C power) with a constant speed feature - it draws more current under load to maintain a constant rpm. Not a comparison to a screwdriver, just pointing out a parallel.
