Step 1: New Motor ?
I found a old motor, saved from a old washing machine with 1/2 Hp and running in 127Vac.
Step 2: The Mill
This is a standard grain mill, with the handle removed, and attached a pulley with 150mm diameter.
Step 3: Wooden Stand
With an old wooden stand for CPU, I decided to adapt and fix the mill, including a new wooden support.
Step 4: Cut and Paste
For this I cut and pasted a new piece of wood, trying to leave with a nice appearance.
Step 5: Appearance
The quality was not very good in appearance, but is very functional and fixed.
Step 6: Motor->Add()
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.
Step 7: Enjoy the Mill
The relation between pulleys wasn't calculated, but I imagine around 120 rpm in the mill axis.
Step 8: First Test
The belt is loose, if a crash occurs, it simply escapes, preventing motor burn.
