The Most Advanced Neck-Turners — Blake IDOD and AUTODOD
Bryan Blake, a very clever machinist and gunsmith, has created an ultra-precise and speedy neck-turning machine. Bryan, who runs Blake Machine, Blake Barrel, and F-Class Products has created a system that uses twin precision cutter tips to turn case necks inside and out quickly and efficiently, with superior precision. This advanced IDOD Neck Turning Machine holds cases securely in a precision-machined spindle attached to an electric motor. Twin blades move precisely during the cutting process, milling the necks inside and out. The turned necks come out perfect every time, with the shoulders trimmed exactly (with doughnut removed) as well. If you turn hundreds of cases during a shooting season, you may want to consider getting an IDOD from F-Class Products. Bryan was able to turn 30 cases in just 6 minutes. And there is an even more advanced version, called the AUTODOD, shown in the last video below.
Our friend Erik Cortina recently visited Bryan Blake in Phoenix. Erik saw the IDOD in action and was impressed. Erik notes: “For a very long time, we have been turning brass the exact same way. Use a mandrel as a pilot and have a cutter with a specified gap go around the perimeter and turn the necks to specified thickness. The IDOD uses a technique called ‘pinch turning’ to turn the ID and the OD (IDOD) at the same time.” You can watch how it works in Erik’s video below (action starts at 7:55 time-mark):
The secret to the efficiency of the Blake IDOD is a vibration-free motor, high-mass case-holder, precision OD/ID-adjustable cutter, along with an advanced tracking system that moves the cutter heads towards the case neck (and back again) with absolute, 100% repeatable precision. Watch the video from 8:30 to 10:10 to see Bryan explain how to adjust the system for a perfect result.
This shows how to set up the IDOD Neck-turning machine for a particular cartridge type:

This latest video from Blake Machine shows the new AUTODOD machine with power controls. This speeds up and simplifies neck-turning process.
The circular orange cutting fixture on Erik’s Milling Machine is a Don Nielson “Pumpkin” neck-turning tool. Don designed this tool to be used by hand or with power. The Pumpkin boasts an eccentric mandrel that allows the cut to be adjusted easily in precise .0001″ increments. Benchresters like this as it allows for very precise control of cut depth and neck-wall thickness. 
You have to admire someone with serious do-it-yourself skills. Not just hammer and nail skills, but formidable design and fabrication skills. Well Forum Member Dave D. (aka “AKShooter”) has a DIY skill set that might put some trained machinists to shame. You see, “DIY Dave” crafted his own pedestal front rest from scratch, using his own design and about $100.00 in materials (not counting the Edgewood front bag). Dave estimates he put 20 hours of labor into the project, but the end result was worth it: “This Do-It-Yourself rest drives like a dream. I’ve played with the Caldwell and a Sinclair, they have nothing on this one.”
