Howdy,
I'm thinking about motorizing my JSP Maltmill, but I'm having some
difficulties finding a reasonably priced source for motors. I
understand I'm looking for something around 1700 RPM and 1/2 HP, but
the few places I knew to look (such as McMaster-Carr) were ~massively~
overpriced for my needs. :)
Anyone have any recommendations on where I might find a good price on a
motor?
Thanks for the advice!
-Sean

Apparently I live a very sheltered life... :) I hate to admit it, but I
don't know what a "surplus house" is. Would you mind elaborating?
Thanks.

A "surplus house" sells surplus inventories from manufacturers and other
places. For the purpose of this discussion you want this item from the
Surplus Center in Lincoln, Nebraska.
http://www.surpluscenter.com/item.asp?UID=2006081614392429&item=5-1086&catname=
This is a 1/4 hp Bodine motor, generally the first choice (after power
drills) for motorizing grain mills.

A place that sells surplus...a good ploy would be to try and type the
word "surplus" and "motor" into google and see what you can find.
Cheers,

I use an electric drill. 115V, 1/3HP, 3/8-in chuck that grips the
shaft nicely, twenty bucks from Harbor Freight. It unships for other
uses, and leaves the mill in its original, easy-to-store, size. You
do have to stand there and hold it while the grain roars through, but
that's just a matter of seconds.
As to the power issue, I've twice (over a span of several years) had
to stop and manually reverse because of stones; a scarred or bent
roll needn't be a catastrophe, but I'm glad to have avoided it anyway.

I'd be careful running full bore with a power drill (or any other kind
of motor). Hitting a stone or other hard item CAN be bad news,
particularly for geared mills, but even for non-geard types.
Speaking from experience, I have a non-adjustable Schmidling with a
slighlty bent shaft and damaged bearing from just such an accident. The
mill still works, but the driving o-ring had to be replaced and the
whole thing's fairly shaky. A slip clutch (I think that's the term) on
the drill or motor can prevent this kind of thing from happening. Combo
drills/screw-drivers usually have these.

I drive mine with a v-belt and pulley. I've never had a problem with it,
but theoretically if it hit a rock the motor would keep running but the
v-belt would slip. Yeah, I can see where a direct drive system (either based
on a motor or drill) can cause problems if you hit a rock.

My electric drill has an adjustable clutch, when load gets too high
(stone) it clicks, no damage. IT's a DeWalt, but most have it.

Do what I'm going to do. Watch craigslist for a used benchtop grinder.
I saw one just before I left for 10$- 3/4 hp. Even derating the hp
50% it's got enough power- and it's already got all the attachments you
need to hook it up- including the guards!

What about a garage door opener? Those are 1/4HP or 1/2HP right?
And you could have a directional remote too :)

Depends on how they're geared in the opener. The motor might not have
enough RPMs to be effective.
My motor came from an old sump pump. We had to replace it because other
parts broke, but if you tear it apart it's built around a simple 1/4HP
electric motor.

Check out some of the surplus houses. Try for at least a 1/4 Hp for best
performance...

Yards that sell used machinery have usually got stacks of them that have

One more possibility - blower motor from a furnace. You'll need a
couple sheaves (pulleys) to reduce the RPMs which can be found at
Grainger, Ace Hardware and many other places. Several articles on how
to figure the sheave diameter for RPM reduction.

Go to a junkyard and get a washing machine motor. 1/2 hp and plenty of
torque. I can fill the shute of my Valley Mill(that I love btw) with
7lbs of grain and go from a dead stop to grinding.
Of course you'l need the pulleys and sheave. I think mine is 12" at the
mill and 2" at the motor for ~ 300 RPM

Aren't the mills designed for hand cranks? I'd be surprised that you would need
a 1700 rpm 1/2 horse motor. It would seem like a lesser motor, geared down
significantly would have plenty of power for the job, and better match the
designed hand-crank speed.

I got the motor, sheave and belt to motorize my JSP for a total of about $20
