I have a Bullet sizer that I made from a Lee press and although it works great with a bulletfeeder on it, My arm gets tired from pulling the handle so much Actually it sizes on the upstroke so its not as easy as my star sizer is which does it on the pull stroke. I want to automate it and have been looking at electric motors and gearboxes but am not sure how much force is required to size a bullet other than what I can "feel" by pulling the handle. Im not sure I like the air cylinders as they dont seem as smooth running as a geared motor is. It will more than likely be attached directly to the top of the ram, not on the handle.
here is a short vid of the sizer I made.

I was looking at this gearbox

And this motor

But the specs on the gearbox say it has 177lb-in of force, which is only about 15 foot pounds? Doesn't seem like that would be enough force?
Please post up pictures of your homemade sizers if you have any. And any recommendations?
