Nice but I might have made a straight tall sanding area that was vertical, or depending on what this is used for looks like sharpening knives made it so you could change the bottom horizontal side to vertical or horizontal positions. This could be done pretty easily with a pivot point at the drive wheel. and lock into an up or down position you could also have used a dc motor off a treadmill and added a rheostat for speed control Most of these motors are 1.5 to 3.5 hp and can run high speed or low speeds with less loss of power, that's a AC motor and without pullies you can't change the speed without loosing motor power unless you but a v belt type pulley system on it. I'd also think about safety guards.
