Default Motorizing my mill

Fellow brewers,

I am going to be purchasing a mill (finally) and I would like to motorize it. Any thoughts if this drill would work? Also any other recommendations?

This is the mill I will be purchasing. http://www.beer-wine.com/products/ba...l-w-7lb-hopper

That link only takes you to the main site. Are you looking at the AC Delco?

It says it runs at 550RPM. While slower than most drills, it's still a tad fast for milling grain. You really don't want to go much over 300RPM and that's on the high side. Should shoot for about 200RPM

Are you set on using a drill or could you use a motor?

If not, look into something like this.

Then look into reducing the RPMs through the right pully combination.

Looking at a calculator, you would be good with a 1" drive pulley and a 12" driven pulley. Should give you about 280RPM.

I'd love to have an actual motor that I could mount. That way I could turn it on and just leave it while I do other stuff. Ill definitely check that out.

Edit: I checked it out, $20 is definite not a bad price for that. Where would I get the gear parts from? I assume the 1" goes on the motor and the 12" on the mill?

Keep an eye on estate sales / garage sales. I picked up a 1HP motor for $10! It rotates at 3450 rpm but if I run a two belt setup, I can get it down to 230 RPM. I will come off the shaft with a 2" pulley over to a 12" sheave. That shaft will also carry another 2" pulley and be powering a 5" sheave that then drives my mill at 230 RPM... I plan to put it all in a pre-built cabinet unit from the big box store... or something like that anyway.
