Over the weekend my son and I put together a motorized
malt mill. I’d been planning it since Jim Suchy gave me
a washing machine motor just before he left. The parts we
purchased cost less than $25 and it took about four hours
to make, with Ben’s help.
The motor is 1,729 rpms and we adjusted it with two sheaves
at 1.5″ and 8″ down to 324 rpm and attached it to my Schmidling
mill. It grinds a pound of grain in 6 seconds.
Im looking forward to brewing this week.
Dan Jeska replied with a couple of photos: Steve, that looks very similar to the mill I have. I used an 1800 rpm
utility motor reduced down via the sheaves you mentioned to around 300
rpm. I have never heard of those wheels or pulleys referred to as
“sheaves”. You will be now be able to use your arm strength for
lifting fermenters instead of crushing grain!
