Does that help?
Mike; yes it does and thanks for posting.
I sure like your hopper it's great looking and simple, how many
pounds of grain will it hold in one filling?
Can you PM me the dimensions of that hopper, it fits my tastes a must have
design with its looks, needs and function.
I believe my email address is available thru my PM. Thanks.
That looks like a fully sealed Industrial motor you have fo your mill.
The gut numbers I started with I will still use keeping
the mill at a lazy 89 RPM's with a short jackshaft across the gearbox
for the 28 to 9 ratio rpm increase plus in a small compact package.
At the opposite end for the 1/2" jackshaft a LoveJoy coupling mated to
the mills input shaft. Direct drive to the bushings without
any side loading forces on those small bushings. From my first look at a MM
I had plans to build a drive system without a large pulley being in the way
besides the bushings side loading was out of my intended design from the
very beginning. Now if the Monster Mills end plates had a bore with a counter bore
to hold a flanged ball beaing instead of oillite bushing this would be no problem with using
a belt drive speed reduction and bearing wear vs bushings plus a lot longer mill running life
ball bearings vs bushings. Even the factory set top roller clearance would not change running
with ball bearings vs bushings as they slowing wearing away because of the grains side force with
dust and dirt getting into the bushings and the shafts load bearing surface area. I'm talking of the
use of double sealed not just shielded ball bearings here.
Everyone I know in CT and Virgina are still in rain for a solid week.
