Dear friends, I have made some modifications to the hand grinder to make it an electric grinder and share it with you. I made three styles of equipment :D :D :D

Nicely done and they look very pretty. I assume the motors have variable speed operation, which is also a nice feature. 8)

Yes, it does have this feature. But because of the problem of heat, adjusting the speed becomes less practical. So I later removed the rev adjustment function.
