Would like to eventually motorize my mill also. I noticed you said you "geared" it to run at about 200rpm. Is that considered a good speed for milling? I have no clue. I use my cordless drill on the "driver" speed.
Thanks
Yeah, in my research I read 150-300 is about right. If you get faster you get a lot of flour and crushing of the hulls which as you know can add astringency to your beer.
The bigger factor though is that the 14" pulley is very common, therefore cheaper. Bigger is far more expensive And the next size smaller in the common sizes would have it running too fast.
