“My friends built a rotisserie (or spit roast) from a junked BBQ, washing machine, and rheometer. It worked surprisingly well.
The remaining parts were salvaged from a junked rheometer. Instead of installing a switch, the motor is controlled by the original washing machine dial. This is purely for esoteric appeal – the washing machine periodically needs to be set to the spin cycle to keep the spit rotating.” – Link.
