I swear I saw a picture of someone with a crazy pulley setup that ran a grain mill with power from a lathe. Now I can't find it!

...Of course, if my drill fails to power 25 lbs worth of rollers, I may have similar pictures of my own!

Fix a pulley to a bench grinder to drive it. Bench grinders are generally more powerful than a drill.

The lathe thing was a bit of a joke - I've got a 1/4 horse motor standing by that'll probably do quite nicely.

Yuri, you might want to restrict the 'inlet' from your hopper when using the drill motor. My 3/8's Milwaukee barely starts my Tortilla press with the 3" aluminum rolls and a 4" intake throat. Usually a jack shaft is used to get mills down to about 350 rpms, 1725rpm 1/4 hp ought to do it. Pully ratios of 2:1 and 3:1. Big pulleys make belts last longer, try not to go to the dinky 1 1/2" ones for the little sides.

Oh, and nothing wrong with heavy rollers- the fly wheel effect will actually make them use less horsepower.

I got so excited about the parts for the conical fermenters that I kinda dropped this project for a few days. I'm gonna finish it tomorrow. Here's what I got done tonight:

Finished both sides along with the steel eccentrics that hold the bushings on the "dead" roller side. The off-center hole allows me to adjust the gap from 0 to 3/16."


My first test powered test run! My 1/2" chuck Black & Decker drill powers this thing with ease! You can't tell, but I took this picture with the drill running at full speed (750 RPM). Even at less than half speed, the drill shows no sign of bogging down. I was all set to order some gears for a 3:1 reduction, but I think I'll save the $40! That 1/4 horse motor I mentioned is going to power the water cooler for my TIG welding rig as I originally planned.


Now I just need to add some set screws for the eccentrics, a top, and a hopper. Should be a piece of cake from here! My next brew is a 15 gallon batch with 31 lbs of grain. I think that'll be a suitable test, don't you?

I use a high torque drill that has a set speed of around 450-550 rpm. Works great.

I don't think I'm going to get around to the hopper today...too many interruptions. I did get the whole frame put together, though. It fits very nicely on top of a 6.5 gallon bucket.

How are you keeping the eccentirc bearings in place?
