I am listing my 21'st Century 3 way trim kit mounted in a 21'st Century Neck turning lathe. The 3 way trim kit is for 22 cal case necks. It trims to length, and performs the outside and inside chamfer, all in a single operation. I set it up in a lathe I had, and it has never trimmed a single case. Absolutely brand new trim kit. Per the 21'st Century website, it sells for $234 and does not include the lathe (it costs $199) or the shell holder/driver (it costs $41.50). I will sell it for $250 shipped including the lathe and oak block it is mounted to, and you will be working your way through your 223, 222, or whatever cases you set it up for in a quick fashion.
Set up properly this will allow the user fast, accurate, concentric and repetitive three-way trimming of cases. The three-way trimmer kit is available for both the standard and powered version of the 21st Century Neck Turning Lathe. Trim Length is achieved via a special stop that is engineered into the lathe assembly. On the powered version this stop is placed on the base plate of the lathe. On the standard lathe the stop is added to the driver shaft rod. Both stops offer macro and micro adjustment to achieve desired trim length. This set-up is so accurate you might want to get a micrometer to measure case length!
The kit utilizes the same tail assembly with free-floating case holder and driver and as the neck turning set-up. The difference is on the cutting tool end. The neck turning tool it taken off and is replaced with a cutting head that incorporates a special caliber specific arbor with a custom-ground carbide cutter installed that trims the overall length and chamfers the inside of the case mouth. In lieu of a neck turning cutter a carbide cutter is used to chamfer the outside diameter of the case mouth.
The kits for both the powered lathe or the standard lathe comes with the following:
-Cutting tool head with carbide outside chamfer cutter
-Caliber specific trimmer arbor with carbide overall length/inside chamfer cutter
-Engineered dead-stop with micro and macro adjustment
-Stainless steel long driver shaft (for standard non-power lathe)
-Three Allen wrenches for adjustment
