Excellent. I love when a project comes together with parts on hand.

you should be fine.
IIRC, that right angle drill attachment you are using is geared at a 2:1 reduction. You could easily double the mill speed by eliminating it, provided the gear motor puts out enough torque without that reduction.

just upgraded from a corona hand crank mill
i work at a john deere dealership and found a customer who had a roller mill he was no longer using.
a mechanic friend at work mounted it on a table with a 1/3 hp motor.
i made the chute and shields but the motor was too weak - could only put a handful of grain in at a time or the roller jammed.
i got a free 1 hp motor from another mechanic at work and hooked it up today.
just need a belt and a welder to weld the drive sprocket( i tried to braze but failed)
and its ready.
the rollers are joined by a chain so they run at slightly different speeds.

Rod,

I am running a roller mill that looks very similar, except that it is belt drive driven by a 1 hp motor with a 2 speed switch. I ended up torching out the dampening springs and making the adjustment screw solid. I was getting some variation out of the crush and found out on mine the spring would compress and not push the roller back. Since then it is working great and delivering a great crush, got the rollers currently set @ .030 but going to open up to .035 to soften it a little and help my sparge. I'll try to slip out and take some photos and add it to this thread.

I used to work at a JD dealership as well. I went to the JD Tech School in NE Iowa for 2 years then worked at a dealership in Missouri. Mainly worked on engines, powertrains & electronics of the large chasis and 4 wheel drive tractors (7, 8 and 9000 series). At times I sure miss those days.

yes - i think i will move the 2nd pillow block closer to the drive gear.
i have a reversing switch but could't figure out how to attach it
see:
http://www.homebrewtalk.com/f51/electrical-help-needed-162830/

edit for update:
moved the pillow block and hooked up the drives - works great - even chewed through the test handful of birdseed with whole corn and sunflower seeds like it was nothing.
did a barleywine -22 lbs of grain -under 5 minutes to crush it - took an hour with my old corona hand crank

Nice builds everyone. MrH, I like how you have the scale and scoop holder integrated.

Here's a pic of mine before I mounted to the wall. It's Monster Mill MM3 with a 180 in/lb 154 RPM gearmotor made in 1974. Found the motor off of surpluscenter.com. It starts up easily even when fully loaded with wheat.

I used PJ's wiring diagram: http://www.programmingjobs.com/images/Bodine_motor_wiring.jpg. I had to ohm out the 3 way switch to figure out which posts to wire.

So I am starting the build of the Monster Mill for my store. I am using a 1725 rpm 1/4 HP "C" face sealed motor. I am going to a right angle industrial Falk gear box @ 7.5/1 will spin at 230 rpm. I will post up a few picts tomorrow eve when I get it all set up and running. I test ran the motor/gearbox tonight and I think I could run a 12" with this set up. It has so much torque, it's crazy.
