I've tried numerous different Neck Turning setups in the past but this one is by far the best so far! It is fast, easy, repeatable, and holds the neck wall within .0001" (+/- .00005")
The Turner is a K&M with the Carbide Mandrel. The carbide mandrel protrudes out the Turner Body far enough to be chucked up in the tailstock. The 5C collet is a 29/64ths and has a depth stop in it set at 3/16ths. The tailstock isn't locked down and will just slide on the ways with about 3-4 #'s force reqd. to move it. The lathe is set for 190RPM. The 220 Russ Brass has been; fireformed with wax, FLS, Trimmed to Length, and Neck Expanded with K&M Expander. I have been doing 6PPC-.262NK Brass with two cuts. First I cut the whole batch to a neckwall of .011", then readjust Neckturner and turn them to a neckwall of .0087"
To Use; I put a dab of Dohrmans Die Wax on mandrel and start the brass on the mandrel. I then just slide the tailstock till the Brass contacts the stop in the Collet. I tighten the collet chuck, switch on the lathe, and start advancing the tailstock wheel. I stop advancing the tailstock wheel when the tailstock starts moving away from the spindle because the shoulder on the carbide mandrel has contacted the end of the neck. I reverse the tailstock wheel till cutter is off of brass then just slide tailstock back. Loosen collet chuck and remove brass. REPEAT -REPEAT -REPEAT -
Typing this up takes ten times as long as doing it. Takes me 45-50 seconds per piece of brass.
I think the advantages of chucking up the Neck Turner in the Tailstock are:
1) The Neck Turner is advanced with no cocking pressure.
2) The advance is smoother using the Tailstock Wheel.
3) The bottoming pressure is the constant 3 to 4 #'s reqd. to slide Tailstock.
