I feel as though I'm posting this in some obscure corner of HBT being in the "Other" slot in the DIY section. Hopefully it will find those who can use the information within.
So after lots of thinking and pondering, I finally decided to build my own grain mill rather then shell out the Mula for a Monster. I often am killing 50#+ of grain a day and the current homebrewer mills just don't cut it for me. So, off to the machine shop I went.
On the way to my shop I picked up some 3" rhot rolled round bar and some flat steal stock for milling up the bearing blocks. The angle was some stuff we had just laying around.
Bearings were some left over from a CNC mill I built a while back. I want to say they are 45mm x 15mm
Rollers are 2 7/8" by 10" long. Shafts are 5/8" dia.
Bearing blocks were milled from 1"x 2" bar stock and are now .75"x2"x3"
The first pic is of descaling the round stock, then putting the knurl on it.
The next pics are milling the bearing blocks on the CNC, and then them after they were finished. The next images are test fitting everything on the new frame. The motor is a high torque 1HP split phase. You can see here my first pulley arrangement. I had one marked 4 inch I just grabbed out of the bin, and swung by the store and bought one marked 2". I figured a good starting point was at somewhere around half of the motors 1750RPM. Of course the 4" pulley was actually 3.5" and the 2" pulley was actually 2.5" so my gear ration ended up being 2:1 it was 1:0.784, giving me a speed of 1,249RPM instead of the 862RPM I was after.
The very first run I made flour, and I mean FLOUR. I could have made bread with it. In fact, that might be something I do in the future. lol
Anyway I ended up going with a my next set up which was what is in the next picture. It's a ratio of 6.22:1 so I'm cruising at a nice 277RPM. I get the best crush I have ever had from this set up.
