I usually use my lathe out in the shop to turn necks, but I would rather do this in my reloading room in the basement of my home.

I found an excellent deal on some AC Gear motors. 40 inch pounds of torque and 117 RPM....PERFECT!

I bought one and removed the main shaft which was easily done by removing the gear cover. I chucked it up in my lathe and threaded it 1/2-20 for a drill chuck I bought at Horrible Freight for $3.....

Wired it up and man does this thing work great! The speed is perfect, any faster and the heat builds up rapidly on the brass. Plenty of power. Can not stall it with the largest cut. It will actually twist the brass before it stalls!

Extremely smooth running motor. I chucked up a piece of drill rod about 12" long and there was nearly zero visual run-out at the end.....

Let me know what you think....Is there a market for these at $200 each?





I still need to put it into some type of bracket or case.........Stay tuned!

Looks Cool!

Congrats on using the old noggin there.. pretty ingenious!

Maybe, but not for me. I use my 1/2" Dewalt battery drill exactly the same way. And, when I finish, I can still bore holes and drive screws!

I believe there is a market. That is the perfect motor for working with cases.

Take a look at 6mmBR.com on the daily page (or one page older). Twenty First Century has built something similar that has a few features that you might want incorporate.

Electric drills and screw drivers are hard on my wrists. Also, the batteries crap out quickly if you are working on a large pile of brass.

It might be interesting to see how you like the motor when you tighten the chuck around a Sinclair, Int. case holder. Also, you can chuck up a carbide primer pocket uniformer, a flash hole deburring tool, and so on.

Sinclair sells a high torque, low RPM case prep unit for well over $300.00.

We will stay tuned.

Anything that will fit in a 1/2 chuck and works at 117 RPM will can be used.

I agree

I use a cordless screwdriver with a Sinclair case holder. I hold the cutting tool in one hand and the motor in the other. It's pretty quick.

Here is a website for 21st Century reloading: 21st Century.

Note that their motor runs just a touch over 185 RPM.

You may be onto something in the land of slow turning motors.

Keep us posted please.

Nr. Nielson (I think it is Don Nielson) of southern California has been selling a similar but smaller cartridge case lathe to benchresters all over the world for about 20 years or more. It is extremely well regarded by the BR clan.

He also makes the "Pumpkin" neck turner, which many winning benchrest competitors consider the ne plus ultra of neck turners. Nice thing about the pumpkin is that it is marked for 1/10,000th of an inch increments. A person can set it exactly where he wants it, then change the setting for some other case or chamber, then come right back to where it was in the first place without a whole lot of cut and try fiddling around either way.

If you do go ahead and enter the market, I would suggest putting a rheostat in the electrical supply line so the user can set it at the RPM speed he or she wants. I would also suggest some kind of a "Quick Change" case holder that cannot mark the exterior of the cases. (A collet chuck of some kind springs to mind.)

Yep that's correct Don up at the San Gabriel BR School .
