I picked up a used crankanstein 3D from a fellow HBT member and as usual over did it on the end product! I have a buddy that was able to help me out with the aluminum and a local welder (I am only set up to weld mild steel) who majorly hooked me up. I will post more pics from start to finish but the basic parts list is: 1 Dayton Gearmotor used from CL ($30), 1 Dayton Drum Switch ($30), 1 used barebones CrankandStein 3D ($100), bunch of free aluminum and a whole lot of time! The motor may be underpowered at 1/6HP and 46 in lbs of torque but we'll see......

Very nice!

Do you know what gap it is set to? 3 roller mills are torque hogs, especially at tighter settings.

I think it's set to factory when I initially checked it, I also haven't found a good primer on how to adjust the 3D. Milled grain samples were pretty close to my .040 barley crusher. Trying to get this right so any pointers are appreciated, next weekend I have 60lbs to grind for a 20 gallon batch of Belgian dark strong.

I have my mm3 set to .0032" and I always condition my grains. I get really pretty husks this way and fairly good efficiency (86 - 89%). I constantly recirc my mash so the nice husks are helpful in maintaining a good flow rate.

cool. thanks! I also do a constant recirc of my mash, my efficiency is usually in the mid 80's so I wouldn't mind a little boost. I'm going to grind 5 lbs or so to see if it binds up, the good news is that these motors are really expensive and torquey and I got two of them for $60 so worse case scenario I sell both of them and get one new 1/3 or 1/2 HP version as they use the same bracket and wiring....
