This mill sets the pace with three fully geared rollers,
index shifters, 1/2" driveshaft, and a precision crossrod for solid performance.
There's no need to pay good money for less
when you can have the Gear Triangle.
Dual stainless steel adjusters click through 9 positions
changing the gap .005" each, factory preset .045", adjustment ranges from .025" to .065".
The three rollers are 5-1/4" long, 1-1/2" diameter, cold rolled steel, with diamond knurled surface.
Grain crushing gears pressfit and welded
Aluminum frames, SAE-841 bronze bearings,
eight 1/4"-20 mounting holes, bolts included,
1/2" diameter tool-steel driveshaft with three flats.
I'd like to thank these guys for doing a well thought out discussion:
