I'm considerin orderin a K&M Neck Turner to add to the Sinclair NT-4000 I have, but was curious what the pros/cons are in have the K&M as opposed to another Sinclair NT-1000, which this second turner will serve as pass #2 as opposed to continuously adjusting the NT-4000.


Advice/Suggestions/Opinions Welcomed...

JD, I have never used a K&M neck turner. But I have used brass that was turned with one. It looked good. I do know some guys that use them and love them. I use a Sinclair for my first pass and a Pumpkin for the second pass. I will use nothing but a Pumpkin! You could not go wrong with either one, in my opinion anyways.

jd ...

I have two K&M turners and enjoy the micro adjustments they provide. If you decide on K&M make sure you also use the K&M expander (if you expand) and the K&M mandrels. :)
 
The K&M is the second tool I've used and I love it. The only thing that I do not like at times is how fine the cutting setting can be set.

440 turns per inch, from their website. what has happened is after the first cut I can not get enough travel for a second cut, and the adjustment screw must come all the way out and start it over on the next thread.

Guess this can be good or bad, depends how you look at it.

Criteria ????

Our thoughts concerning "neck turning" vary quite a bit. At one extreme, many believe anything less than perfection is unacceptable. At the other extreme, where I live, the task is no more than reducing the neck thickness such that a loaded round chambers with neck clearance. If a tool was available without adjustment set at .0085 I'd be a candidate to buy one.

The K&M turner is capable of satisfying either extreme .... as well as any of the other "popular" tools.
 
K & M turner

Have and use both the Sinclair NT1000 and the K&M. Since I have difficulty getting repeat settings with the Sinclair, I keep it set for .0085" for the 6ppc with 220 Russian Lapua. All other turned necks are done with the K&M for the varience in neck wall thickness. Do have a problem with the screwdriver type handle of the K&M always coming lose, no matter how tight I make it, so prefer the Sinclair cross T-handle for all turning. Seems like the new Sinclair has corrected previous limitations, and I'd buy one if i did not already have the other 2. As with most "things", few are perfect.
 
I have both and use both. The Sinclair is used for the first cutting and then the K&M. The K&M has a reamer on it's cutter pilot which will remove any donut inside the case neck. I love the way the Sinclair shaves the brass, very much like a lathe, but the K&M cuts deeper into the neck at the shoulder junction better for what I want at least for the 30 BR. Randy J.
 
I like to cut brass at high speed.

Although this is against conventional wisdom, I turn necks at high speed. I use two K&M turners, a Craftsman variable speed drill, and RCBS case lube. I was once told by Jim Carstensen that it makes for a better cut if brass is cut at high speed. I have found this to be the case. However, one must have a proper fitting mandrel on his turner, and use good lube. I have have tried many lubes, but the RCBS has proven the best that I have tried. Good shooting...James
 
I think I go against the norm sometimes. I turn my brass at high speed (like James with a craftsman), one pass, then set the turner in some water, do the flash hole, then the primer pocket, then pick up the next case, chuck it in, use whatever lube I have handy, pick the turner up out of the water and do it all over again. Turner has been set the same for five years. I do about 500 cases a year and it has not lost adjustment or changed the cut at all. Neck variation usually runs around .0001 after turning. One thing I have learned, is watching for the right feed speed. The brass should come off looking like a spring that is spaced slightly larger than the width of the cut brass. Any tighter, to fast, any more, to slow.
