  1. NOW SOLD £85 for job lot posted to mainland UK including: Neck turner tool body with cutter (£65), Power adapter(£31) , Power adapter handle (£16), Press adapter (£16) All you need to neck turn your cases by hand or with a normal power screwdriver - just add a calibre specific pilot (£17) and expander mandrel (£17) available from 1967spud.com I have pilots and expander sets available for 6MM and 6.5MM for an extra £20 per set. Full instructions and setup videos at: https://kmshooting.com/learn/ From the manufacturer: "The K&M neck turner has a very unique cutter adjustment mechanism that allows for a very precise cutter adjustment. This design incorporates very fine pitched threads of a screw within a screw concept which yields 0.002” cutter advance for each rotation of the adjustment nut. As a point of reference and comparison, a micrometer advances the spindle 0.025” for every revolution of the thimble. There are etched markers on the neck turner body around the circumference of the cutter adjustment screw hole placed every 30 degrees radially and as a reference, there is one punch mark on the face of the adjustment nut. When the adjustment nut is rotated one increment the cutter advancement is 0.0002”. You can drive the cartridge with the power adapter and proper shell holder by hand when the handle is installed or remove the handle from the power adapter and insert the ¼” hex stem into a cordless screwdriver."
  2. I finally decided that I’d have to turn my necks if I wanted to totally standardise my neck tensions and seating force. I’ve always been fussy about it but never felt the need to spend the money on all the neck turning kit as I was able to get good ES by being careful to monitor my seating force, lately becoming extremely fond of the K&M arbor press with the force dial indicator. Yet things get complicated when you start to add some brass flow in to the equation and donuts raise their ugly heads. Neck turning seemed the way to go to totally standardise my necks and solve my brass flow issues. I could also standardise my neck tensions between differing makes or lots of brass. I wanted a system that was fast, easy, precise and also cut into the shoulder. Everybody normally seemed to be worrying about how much to cut into the neck shoulder junction. I very much liked the idea of the cutter being angled just right so you could cut up the shoulder just so. I definitely wanted to use a power tool to do the feeding – turning a piece of metal with the variable speed of your wrist’s uneven turning motion? That seemed a very difficult proposition! I can barely chamfer a case neck evenly by hand so I didn’t fancy turning whole necks without even and controllable speed. I came to the 21stcentury turning tool because they are making some really progressive kit and their take on things is always worth considering. A look at the youtube videos and a chat with John there had me convinced that their turning tool mounted in their little lathe mount was the way to go. The cutter depth dial on the tool is easy to set up as it doesn’t have a locking nut that slows the adjustment process and creates backlash. There is a dial that means you can take note of exactly where it is when each calibre is set, making set up nexk time much quick and more precise. The floating mounting system of the lathe seemed to enable self-alignment and the ease and speed with which John was turning necks on the videos looked like magic! A few seconds to turn to a fifth of a thou? Just the ticket! The carbide cutter can be swapped for one that matches each calibre’s shoulder angle. This means you can just kiss the shoulder a mm or so and know that you’ve got that neck to shoulder junction clean again. Brass from inside the neck will flow into this new space and resolve any donuts that have built up. If you don’t think your 5x fired brass has donuts try dropping a long bullet into a fired case – you may be shocked! If you feel any resistance you need to solve the brass flow. The neck is supposed to be a tube, not a cone! My tool arrived from the states and I eagerly started expanding my brass with the expander mandrels. For novices such as myself, I’ll explain this: the turning process requires that the brass be at just the right size and the way to control this is to resize it with the turning tool manufacturer’s expander mandrel. This is simply a calibre-specific rod that fits in a die in your press in the normal manner. You quickly run the press and it sizes the necks just right for the turning process. Different calibre inserts fit in the same die in seconds so you only need one die for all your calibres. I couldn’t resist the super low friction titanium nitrite ones – they’re gold! Just as a calibre-specific rod is used in the expander die, one is also used in the turning tool. This guides the case on straight and is just the right size. Again I went for the cool gold one…. This is slid in and out during set up as it acts as a depth stop ie it controls how far down the neck and into the shoulder you can feed the cutter. Once this is set up using the lock nut and depth adjuster (allen key provided) you are good to go. The driver which you attach your drill to has a beautifully designed shell holder suspended from it. I say suspended as it is free to move in every direction so that it can self-centre. This is the real genius of this lathe set up from 21stcenturyshooting. The machining is sublime and the way the shellholder nips up by hand without harming the brass is just wonderfully done (there is an o-ring that gently binds to the case head) Changing to a different calibre shell holder does not take long. A driver for external use ( like annealing) is provided too: Then one simply attaches the drill and feeds the case on to the alignment arbor and into the turning tool. Controlling the speed with the drill, you turn the case. The shellholder and the tool both will self-align and become perfectly aligned. Note the rubber bushings allowing the tool to float: In a matter of seconds, you have a perfectly turned neck and the shoulder shaved at exactly the right angle. It is an absolute pleasure to do. I got bored of measuring the results – the results were frankly perfect. I was turning to 13.7 thou (0.0137”) and with my neck micrometer I could detect no variations from that whatsoever in dozens of cases. The tool can be tilted to any angle you fancy. Bottom screw is the angle and the top one is the length stop ie how much you cut into the shoulder Interestingly, when I loaded the brass and came to seat my heads, the level of consistency of the seating force was amazing – neck turning is a must! If you’re debating whether it is worth having to master a new process, spending money on other tools and probably cutting dangerously too far into your shoulder – fear not! The 21stcentury system makes it all totally straightforward to the point of being a pleasure even for the first-time turner such as myself and the potential pitfalls are avoided with ease. The results are certainly worthwhile too – your ES will improve no end and you don’t have to worry about donuts or variations between lots of cases. I haven’t compared this to other tools and I have no prior experience of neck turning. Obviously there are other tools that will do the job but from reading forum posts on the matter it is clearly a complicated process fraught with difficulty, inconsistency and frustration. What I can say about this 21st century kit is that it is not just a tool but a complete system for neck turning. You can buy this as a total newbie and it will give you absolutely premium performance - safely, quickly and easily - taking a daunting process and making it a pleasure.
