I am going to build a grain mill when I get back like thisone http://www.wortomatic.com/articles/Sam's-Motorized-Grain-Mill but the motor I want has been discontinued it was a 117.7 rpm motor from surpluscenter.com, I know they sold another motor that was 105.7 rpm but it has also been discontinued. So I'm just wondering if anyone knows where I can get another one or something that works just as good, any ideas would be appreciated.

Check eBay, you can run across motors in the right rpm and torque range once in a while. Just bear in mind that the shaft size from the motor may be a different diameter than the one in the web page so you may have to get a different sized coupler. I accidentally bought a 3 phase Bodine motor without realizing it off EBay. I'm glad I did now because with a phase converter/variable frequency drive I have absolute control over speed. My point is be flexible in regards to the build and you may end up with something that works for you better. If you go the route I did & need any help let me know. I have a thread on here with my build. Good luck.

This is an old thread, but I'm selling a motorized Barley Crusher with a set-up just like shown on Wortomatic with a GE gear motor. It's listed on eBay:

Buy a cheap 110-120 vac motor (1/3-1/2 hp) and hook it up to one of these:

You can also get an AC gear motor from McMaster-Carr. Then just get a coupler to go from the motor shaft to the mill shaft. At <$55 for the motor (face mount), it's a pretty good deal, IMO. The coupling (to my Monster Mill) would run another ~$38. But with not having any belts, pulley's and such to contend with, it's a viable option. Just need to get something to hold the motor, mill, and catch bucket(s) and go from there.

what exact motor are you referring to for under $55 ??

it looks like you would be stuck at 10 rpm's or so. that is pretty slow, but i guess if you flip a switch and do something else it's not really a big deal.

How do you figure that when the motor is 150rpm?? Granted it's only 5 ft# of torque. Since that's directly connected to the mill shaft, you won't have any loss due to pulley's and belt. Worst case, you start the motor and then fill the hopper. Or set it up and test before the return policy runs out.

"AC Gearmotor W/Fan, Face Mnt, 150 rpm, 5 in-lbs Torque, 115 VAC"

"ft#" does not equal in-lbs.

Are you actually using this motor? Seems like it would be way overmatched by any substantial mill.

The motor itself looks pathetic and 40 in-lbs is the torque you would need (for a big mill); the 25 in-lb model would probably be suitable for a barley crusher. Even still, at 20 RPM's a milling session would take quite some time.

This motor is poor suggestion and the OP would be better off searching Ebay or Craigslist.
