I wish I had built this rotisserie when I first started the chassis, as it really makes the work a lot easier. I constructed this simple home made unit and attached it to the chassis when I got to the paint stage. There are a lot of angles and sides to the multitude of tubes that make up the chassis, so being able to rotate the whole chassis made the painting process so much simpler. And once I finished with it I sold it and recovered the cost of the material.
I would highly recommend the use of a rotisserie from the very early stages of construction. Easy to build, not all that expensive and a very helpful device. Economical rotisseries are readily available to suit home use and certainly worth investigating.
