Flywheel Hand Crank for Neck-Turning
This do-it-yourself project comes from ace silhouette shooter Larry Medler. He devised a hand-crank system for turning case necks that offers the best of both worlds — the speed and “muscle” of powered neck-turning with the “feel” afforded by manual methods. The flywheel, salvaged from an old grape crusher, delivers plenty of RPM when needed, but Larry still has total control over the neck-turning speed and torque.
Larry explains: “My neck turner is a home-made model with a 15.5″ crank flywheel. This arrangement almost makes turning necks fun. I’ve learned that the secret to neck turning is how easy it is to turn the case. If it takes too much force or effort you’re probably not going to do a good job. However, when you turn by hand you have the best feel for the cutting process. So I wanted a system that reduced the effort required, but still retained good “feel”. My hand crank system fits the bill — it makes cutting easy, but you still have good sensitivity throughout the process.
The case holder was made for 308 Winchester cartridges. The case holder fits into a rubber heater hose that connects to a 0.5-inch rod. The rod is fed through two bearing blocks which mount on a frame on my work bench. The rod is turned using a crank on the grape crusher flywheel. This system works great for neck turning. It is easy to crank and you still have a feel for how the cutter is working. While I now use an electric screwdriver to power other case prep tools, at one time I attached a variety of tools to this simple crank system.
I recently upgraded to a K&M Neck Turner (from a Sinclair previously). K&M makes a great tool. It’s easy to make very small adjustments to the cutting depth. I use the K&M case-holder that came with the neck turner for triming cases. It grips a little better than the Sinclair case-holder and both are easier to use than the Lee case-holder.”

Hi!
I used the same load data as posted in this forum by Ric Horst and LSR. I used the 162 Hornady A-Max with the bullet kissing the lands and everything else kept the same. Great blacktail round out to 1100 yards. I personally took a forker at 1150 yards this past season.
