Is there any way you can post your wiring diagram? I'm wondering if somehow I wired it incorrectly, creating less torque?

Mine operates fine in forward and reverse, but as I said, it jammed very easily.

I was using some very old grain, but I doubt that should matter.

Used a belt/sheave with the 3d for years, but I like my current setup more:

I upgraded my motor to a bodine gear motor with 120 in/lbs of torque. Cost more, about $150 on ebay. Was brand new, though. But it works fantastic. Easily started up with 20lbs in the hopper already. Milled 32 lbs of grain for today's brew day.

I'm glad the 40 in/lb motor worked for you. But I'd caution others to try that motor with a 3 roller mill anyway. My only problem was torque. I had mine wired the same as yours, so who knows what the difference was. Maybe the capacitor on mine wasn't working properly. Anyway, here's a pic of my new mill setup.

I think you'll find there was a reason why grain used to be ground by mill "stones" and not mill "logs." That stuff is going to be so abrasive that it will erode the hardest wood in short order.

Here is a picture of my mill.

Take a look a the picture, I have a lot of you have the same motor and I have a question.

Have you add any problems with the motor jambing because you have to much grain in the hopper. I do all the time. I wonder if I need to close up the exit portion of the hopper to limit how much grain hits the rollers at once.

Which direction are you running the motor when milling CCW or CW?

Reason I'm asking is the Gear Motor 5-1098 is designed to run CCW (viewed from the wiring end). If run CW it has far less torque available.

And another thought. If you got this Gear Motor 5-1074 it has far less torque available in either direction as well as a much lower speed.
