Henderson V3 Machine Trims and Chamfers Cases Efficiently
Gavin Gear of UltimateReloader.com recently tested the impressive Henderson Gen 3 (V3) Trimmer. There is a full write-up on Gavin’s website, and you can watch Gavin’s 18.7-minute video review below.
Gavin states: “I met Todd Henderson at SHOT Show and it’s clear that quality control and customer experience are extremely important to him. The Henderson Gen 3 case trimmer is built on an adjustable tri-trim 3-way cutter with different pilots to accommodate different case necks. Three way cutters trim to length and chamfer the inside and outside all at once. This trimmer has a 1700 RPM spindle and a custom DC motor made in the USA. It is made of billet aluminum and has a taper-lock cutting head and is consistent to 0.002″” at least with the same brand of brass. The collets are Brown & Sharpe style collets and are interchangeable with Forster case trimmer collets. Henderson currently offers four collets, and one is supplied with each machine.”
Gavin explains the trimming process: “I had some 6mm Dasher brass I’ve fired a few times and wanted to take down 5-10 thousandths. The Henderson trimmer works much like a milling machine. You do not need much torque because of the way the taper works.”
The Henderson Gen 3 trimmer delivered outstanding cartridge length consistency after trimming: “I was careful to ensure my trimming process was as consistent as possible. I measured the first ten cases I ever trimmed on the unit and found a standard deviation of 0.00047. The extreme spread is actually less than advertised. This trimmer is fast and easy to use and most importantly, returns consistent results.”
F-Class John Review of Henderson Gen 3 Trimmer
Our Editor F-Class John has also reviewed the Henderson Trimmer. He liked the product so much he purchased one, and he uses it regularly now to trim his .284 Win cases for F-Open competition.
John liked the precision of the Henderson trimmer and the overall design of the machine, which offers good ergonomics and very precise alignment of the cases. Cycling is smooth and positive, as you can see from the videos. Fit over the pilot was fine for John’s .284 Win brass, but he notes that other users may need to expand their case necks appropriately to fit their pilot.
Watch the video to see the Henderson trimmer in action. The dual, parallel horizontal support shafts provide precise alignment of the case as it moves inward toward the cutter blade. The Taper-Lock cutter provides a 14-degree inside chamfer and 30-degree outside chamfer. The trimming process is very consistent case after case, and the Henderson’s design captures brass shavings effectively.
