Automatic bullet sizer

[KY DAN]

Been working on the design for a while and think I have a idea.

I know nothing about electronic items..... nothing.

Can someone please recommend a gear motor either 110/220/ or 3 phase that will have the force required to push 1 bullet thru a star sizer style die.

It will run for a minimum of 1qty hour and I would like the motor to run 100 rpm so I could do 5000-6000 a hour.

I hate sizing bullets and this is the only warning know to do it quickly

Bullets will be .311 to .500 inch diameter

Wax lube only

This is a 1/10 hp shaded pole gear motor.

Its not as fast as you want but if you automate the other steps, you can do them all at the same time vs one after another. That's where the most time is saved.

Buy a Lee App press and get their bullet sizer. Mount your gear motor above the press by extending the 7/16 columns and making a face mount bracket. Put a crank with 1/2 the length of the press stroke on the gear motor shaft. You will need a beefy gear motor as there will be a lot of overhanging load on the shaft. My guess would be a 5/8 diameter output shaft or larger. A new motor will be in the 500-1000 range. You might find a few on ebay. Someone on THR has already done this with an air cylinder. My only caution is guard the press carefully or you will cut a finger off.

The cylinder needs to be larger in diameter, that’s a 1” cylinder being fed 175psi and not crimped pockets. I’d rather have too much cylinder and regulate t...

That requires more machine work than just adapting to the press linkage, like that breechlock above but if your into more work, its not difficult to convert rotary motion linear.

This is the first one I built using penumatics.

Collators are key, if you have to sit there and fill/rotate tubes, it takes you away from the other things you could be getting done.

I bought a damaged HD treadmill (brand new) and used that motor to replace the bad one on my hobby lathe, total speed control instead of changing the belt on pulleys and a LOT of torque when I installed a 1-3 pulley system, total cost was >$100. Look at DazeCars on YouTube to see the wiring diagram and see what I copied. I feel you could do the same using some of the ideas from jmorris and save the major expense of the motor.
