Coupling for grain motor/barley crusher

The latter looks very similar to the set I use between gear motor and BC mill, but at around half the price I paid to Surplus Center.

There are set screws in these in addition to keyways. I put a drop of blue Loktite on the screws and I set them on the flats on the shafts at each end. Works fine...

Cheers!

When you buy your lovejoy, you will buy three pieces. One coupler sized for the motor shaft, one sized for the mill shaft and a "spider" to couple them. And yes, they will have set screws.
