Yeah, you have read that in another thread here. So have I. I just don't have access to spare wiper motors from semi tractors. I think that the wiper motor that monsterguts sells for animating Halloween decorations might have enough oomph to do it. I just don't have a torque wrench to check how much torque it takes to turn the mill, with grain in it.

Here's a figure: A LOT. I conditioned my malt this weekend and the drill had a hard time starting (10A, 1/2" drill) on slow speed. Had to crank speed up to keep it going. Dry grain takes less, but it does take some beef on these since they're grinding rather than just squeezing.

Yeah, but when I turn it by hand it doesn't seem like it takes much force. I really want to figure out a way to get a rough measurement before I drop the coin on a motor that might not work. Hmmmm..... I have a digital handheld luggage scale. I could connect that to the handle of the mill and pull it around then do the math from there. That ought to get me close. I've also thought about taking the motor out of one of those harbor freight drills and figuring out a way to mount it. More ideas than time.

Those big semi wiper motors are readily available from junked trucks online....and it's not like I don't have a gigantic 12VDC power supply. It's just that I don't want the level of complexity that would go into that kind of installation.

I can break a bolt loose easier than my drill, too...but I tire faster

Looks to me like:

1. Homer bucket is thin plastic and maybe a bit flimsy
2. The screws look to close together, try spacing the screws as far apart as possible...even it you have to angle them and they will support the mill better.

The homer bucket is pretty flimsy. I used deck screws which have a pretty small head and I am a bit worried they will pull through over time. I have some pan head screws to change them out with and maybe add some sheetmetal. The mill is supported ok I tried tipping the bucket and everything and it doesn't move.

I went with your design so if I get a water bottle for a hopper all I have to do is get a new lid.

A couple of washers should be more than enough to keep them from tearing through the bucket.

Here is my revision. I didn't have any washers on hand small enough so I used some 24 GA sheet metal. Hemmed over the short sides so that when the screws tightened they wouldn't distort the metal and leave any sharp edges. This is so solid I could probably stand on the mill. Plus it adds some junk to it. ;-)

You've got my favorite tool next to your bucket there. I can do just about anything with a set of channel locks. I'm still just clamping my drill on a 2x4 and setting it on the top of a homer bucket. After revisiting this thread I'll have to change that.
