Here are plans for a skuff machine that can built with hardware store parts and a rotisserie motor for a few dollars, provided you have some handyman skills. If the exact construction methods don't appeal to you, hopefully at least I have given you something to think about.
Nothing makes hash better than a rotating skuff machine.
The machine is basically like a squirrel cage, with the pot being the squirrel. Two circular plywood sides are aligned on a shaft, with silk-screen netting between. The cage is rotated with a motor, and the glands fall through the screen to be collected on a base, like a piece of glass, or perhaps foil. A rotisserie motor is perfect. Some Home Base type stores may have units designed for outdoor use.
