Neck-Turning Lathe from 21st Century
21st Century Shooting has just released a new Neck-Turning Lathe system. This is a great product that may revolutionize the way reloaders turn their case necks. Watch the video and you’ll see why. If you’re never turned cases before, you may become a convert after seeing how quickly and easily the new 21st Century Neck-Turning Lathe does the job.
The mini-lathe has unique fittings on the left and right sides that allow both the case-holder and the neck-turning tool to float. As a result this tool maintains near-perfect concentricity during the cut. 21st Century’s John Perkins explains: “The floating design of the neck turner and the case driver allows the case mouth (bore) to run on the arbor absolutely concentric, therefore allowing O.D. to be turned concentric with I.D. The tailstock creates a horizontal inline support for the base of the case. This also allows the operator to keep both hands on the power screw driver or drill, making it very easy to control the feed rate and to produce a very fine, turned finish.” Having the system float at both ends was key, according to John: “By allowing both the turner and the case to float, everything self-aligns. This maintains concentricity and allows the unit to work with very low torque.”
Neck-Turning Lathe is Fast Yet Precise
Using power from a drill or electric screwdriver, this tool will turn necks fast — in a matter of a few seconds. And it produces beautiful, smooth necks that are extremely uniform. Tests show that the lathe, used with the 21st Century Neck-Turning Tool, will hold 0.0002 (two ten-thousandths) neck wall tolerances. And it will do that time after time.
Turn Necks in a Single Pass
Using traditional hand-methods, turning case necks can be time-consuming and fatiguing. Many folks will experience hand pain or cramping after just a dozen cases. Watch the video, you’ll see how fast and easy neck-turning can be with the new mini-lathe. You get an exceptionally good cut in seconds. Very importantly, with this system, you may be able to switch from a double-pass cut, to a single-pass cut. Yes, even if you’re making a deep cut, we think there is a good chance you can turn all your necks in a single pass. That can cut your labor time in half!
Why does the 21st Century Neck-Turning Tool cut so well? First, the Neck-Turning Tool employs ultra-sharp carbide cutters that are custom-ground to fit the shoulder angle of your cartridge. This allows you to make a perfect cut extending down the shoulder 1/32 of an inch. Second, the system aligns the case neck on the arbor (mandrel) so well, and the cutter is so sharp, that very little torque is required. This allows the cutting process to go very smoothly. The case-holder is also unique — it features a O-ring so it holds the case firmly in place without marring or bending the case head. The tailstock case-holder adjusts to accommodate cases from 17 Fireball to a .416 Rigby.
More Case Prep Tools for Lathe in Future
In the near future 21st Century will offer additional case prep attachments for the new mini-lathe. 21st Century plans to provide a case-length trimmer, a concentricity gauge system (with bullet-straightening capability), and other options. These will all work with the same lathe “chassis”, and the trimmer will run with power. John states: “This is a modular system, all parts interchange. So if you have an existing 21st Century Shooting Neck Turning Tool or Bracket, everything will fit.”
The 21st Century Neck-Turning Lathe costs $224.95, complete with Neck-Turning Tool ($78.00 value) and one case-holder driver. The Neck-Turning Tool comes with a carbide cutter with user choice of shoulder angle. Perkins recommends using the Neck-Turning Lathe with power, but it will also work with an optional hand crank. NOTE: Currently the Neck-Turning Lathe works ONLY with the 21st Century Neck-Turner. It will not work with K&M, Sinclair, or Forster tools. But that’s not a real drawback because the 21st Century tool is certainly one of the best on the market today. See detailed review below.
You can purchase the Neck-Turning Lathe (complete with Neck-Turner and Case-Holder) through the 21st Century website, or call (260) 273-9909.
Gear Review: 21st Century Neck Turner
by Germán A. Salazar
A new neck-turning tool with easy adjustments, super-high quality of manufacturing and an ergonomic design sounds like a good thing to me. If you also like good tools and like to keep up with developments in the field, read on (most of the pictures can be enlarged by clicking on them).
I recently received the new Neck-Turning Tool made by John at 21st Century Shooting. I always enjoy seeing John’s work because he really has a good grasp on how a tool should be designed to work effectively and this tool certainly fits that mold. The basic requirements of a good neck turner are: (a) accurate adjustments, (b) good blade design, (c) ergonomic design and (d) a well thought-out system of ancillary items. Let’s look at each of those areas and give the tool a test drive.
Handy Cut-Depth Adjustment Dial
The 21st Century neck turner has a unique dial adjustment for the depth of the cut which makes small adjustments simple and fast. Each full number represents 0.001″ of cutter movement, and the fine lines in between let you zero in on the exact neck wall thickness that you need. The dial is simply turned in until the desired neck thickness is reached. If you go too far, it’s best to turn it out a full turn, then back in once again; this reduces the effect of any backlash that might exist in the threads. I found the dial easy to use and had no trouble getting to my usual thickness setting of 0.0125″.
Excellent Carbide Cutter Blade Design
At its core, a neck turner is a cutting tool and good blade design is what sets any good cutting tool apart from the competition. Here, John really shows his ability as a designer and manufacturer. The blade supplied on my tool is carbide and cuts brass effortlessly, however, that’s not the real point of interest. Many neck turners have blades with less than ideal nose radius and create a “threading” effect on the neck unless the tool is fed over the brass at a very slow rate. The 21st Century blade has a good radius at the transition to the shoulder angle which allows for a smooth cut with a reasonable feed rate.
The shoulder angle is another well thought-out feature as it is a very close match to the actual shoulder angle of the case. This allows you to bring the cutter a bit further into the shoulder without weakening it and definitely avoid the subsequent occurrence of the donut of thick brass at the base of the neck. (When ordering, 21st Century lets you specify one of four (4) different cutter shoulder angles to match your particular cartridge: 20°, 30°, 35°, and 40°.) The photo of the case in the cutter shows the cutter making solid contact with the shoulder after a substantial cut on the neck, yet the shoulder was really just lightly touched. I backed the cutter off a bit from this setting for the final adjustment. If you tend to use heavy bullets which extend below the base of the neck, this feature alone makes John’s tool worthwhile.
Turning necks is tedious, especially if you’re turning a large number of cases as High Power shooters generally do. Accordingly, a design that takes ergonomics into consideration is highly appreciated. Note the slight hourglass shape of the tool, that really lets your hand take a grip that counters the natural tendency of the tool to turn with the rotation of the case, especially when turning with a power case driver. The size of the tool itself also helps; if you’ve used one of the smaller tools on the market, you know just how tired your hand can get from trying to hold on to it after a while! I turned 70 case necks in two sessions with the 21st Century tool and my hand and fingers remained comfortable throughout.
However good the turner may be, it doesn’t work alone. Any neck turner needs a matching expander. The 21st Century expander is a nicely designed unit that allows you to change expander sizes with no tools by simply unscrewing the cap of the die body and dropping in the appropriate expander.
K&M Arbor Adapters Available
I’ve been using a K&M turner for some years now and have accumulated turning arbors (mandrels) in various sizes. John knows that’s the case for many of us, so he makes affordable adapter bushings for his tool that allow the use of K&M turner arbors. That’s a nice feature that will allow me to save the price of a few arbors and expanders. The adapter for K&M arbors costs $12.00.
Although I use a cordless screwdriver to turn the case, I still like to have a manual option for case turning. Sometimes the cordless driver dies with just a few cases left to go in a session and I know that, one day, when I most need it, it’ll just quit altogether. John’s case handle for manual case turning is another well-designed, ergonomic piece that shows his careful, thoughtful approach to tool design. He even makes a version of it for the .50 BMG if your tastes in cartridges run on the large side!
