My first two batches through the barley crusher with drill power had too much flour come through. I figure it is a good excuse to use an old 1/3 HP/1725 rpm motor I have in the basement.
So far the plan is to use a 1.5" (Pitch Dia. 1.05") and a 14" (Pitch Dia. 13.55") pulleys from Grainger.
that will bring the RPM's down to (1725 * 1.05) / 13.55 = 133 RPM, whcih should cut down on the flour that is produced.
For the physics types, how far out should I put the motor to avoid the belt slipping during "normal" use grinding grain?
I've looked at this site: Notes on Pulleys and Belts which has a pretty cool calcualtor, but I haven't had physics for years and I'm not sure what numbers are important and which aren't.
Thoughts?
