Electrified Kinu M47 Grinder

This file contains all the parts you need to make your Kinu M47 Electrified. It's plenty powerful and very reliable. The back can house a power supply to power your motor and fits a standardized switch LINK HERE in the back that can snap in. The motor mount accepts a windshield washer motor like the one I used here that spins at 110rpm LINK HERE. I attached a motor flange that had holes pre drilled for 5mm bolts and was about 5cm in diameter LIKE THIS ONE BUT THIS ONE IS WRONG SIZE. These bolts were used to drive the axle that was printed to fit into the grinder. That file is also attached. The whole grinder is fit together using friction along with 5mm bolts.

This design is not perfect, but it is simple and easy to put together. I have used it for almost two years and have to change the axle occasionally. I would like to make an axle out of brass but have not gotten around to it.

If you cannot find the motor, you could make an adapter to attach to the motor mount.
