This is just a short video demonstrating the rotisserie I built for spraying the finish on guitar bodies and necks. The components were very simple; some aluminum L stock, the power take off from a junked snow blower, a B-B-Q rotisserie kit I picked up for $15 a belt and a couple pulleys. As well as some iron plumbing fixtures and 2 inch steel flat bar.
The concept is to keep the guitar part moving while applying the finish to prevent runs and sags in the finish. All the commercially available products are non powered and cost about $100. I wasn't interested in standing around turning a wheel and watching paint dry so the idea was born.
