Poor's Man Mill


Usually the people that do your beer, or homebrewers, use the manual mill to grind the malt.
Some others use the a drilling machine attached to the mill axis. Works fine but over time eventually damage your drilling machine.


I found a old motor, saved from a old washing machine with 1/2 Hp and running in 127Vac.


This is a standard grain mill, with the handle removed, and attached a pulley with 150mm diameter.





With an old wooden stand for CPU, I decided to adapt and fix the mill, including a new wooden support.

For this I cut and pasted a new piece of wood, trying to leave with a nice appearance.







The quality was not very good in appearance, but is very functional and fixed.



The next step was buy a "VA" belt in necessary length and mount the motor using a metal plate to fix the motor in the wood.








The relation between pulleys wasn't calculated, but I imagine around 120 rpm in the mill axis.


First test:

The belt is loose, if a crash occurs, it simply escapes, preventing motor burn.
