Default Motorizing the malt mill - old air compressor

So I'm re-purposing an old air compressor I found next to the dumpster. The motor works fine. The compressor head was shot and not worth fixing.

Took off the head and started removing the needed parts. Filthy from leaking oil.


Cut the deck off the tank. Had to take apart the mill and flip the shaft around so it would spin right. Brushed the rollers and cleaned up the bushings. Had some rust from a rainy brew day.




Fitting it all up to be sure the guard and sheaves will line up properly.



Waiting on some bushings to shim the shaft. Has 5/8 hole on the sheave and 3/8 shaft on the mill.

So total will be about $3.00 + reused switch box and light switch for on off.

Coming soon - building a box with wheels to move it around.
I plan to remove the motor and clean and repaint the deck after I drill mounting holes and cut the pass through for the grain.

Probably will use a $9.00 furniture dolly to move it around as the stock wheels are cracked.

Doing the math it looks like I might have to change one of the sheaves or use a router speed control to lower the rpm

Most of the stand built. Need to tweak the spacing and rollers.

Tested with the motor and it turns true
