I'm trying to motorize my Crankandstein mill.
I have a 1/2" 550 rpm drill. I sized a belt and pulleys to step it down to 180 rpm.
I got everything put together and started to test it out.
It's running fine, speed looks good. Drop a little grain in, looks good.
Drop a handfull of grain in, mill binds, drill keeps spinning.
I've tried loosening and tightening the belt, it just spins when a fair amount of grain is in.
I widened the gap, with the same result.
I've hooked the drill directly to the mill and there is no stopping it. The speed is just too fast.
I would prefer to use the pulleys, is there something I'm overlooking to stop the spinning?
