Dc motor variable speed controller for knife grinder


This is a nice variable speed controller for the DC motor on your lathe, knife grinder, belt sander, handsaw, or whatnot. Reversing switch on control box. (DON'T change directions with motor running!) Speed is controlled by a dial on the control box.
This will work with any DC motor 90-130v, 1.5hp or less.
