Well you do whatcha gotta do to get the job done. Personally i dont like building anything out of wood. I prefer to zap it together with a wire welder. Fast and strong. That one end i made took me 4 hours. The one for the back end of the car will come together much faster since i got everything figured out on the front one.
Nice thing is i can store the rocking rotisserie ends behind my shop when im done with them , and use em for my next project. Going to dress all the welds, and brush on some rustoleum metal primer to protect everything from rust.
