Hand crank will easily rotate the car once you get the cg positioned in the correct place (that’s what the hand wheels at the top do). Otherwise you would just rotate it manually by hand with little effort. Worm gear drive is nice because you can’t backdrive a worm gear. Adds another element of safety.
I am hoping to have it up and running within the next 2 weeks. Going to grab all the steel on Friday. Casters showed up today, and found the worm gear winch I need locally on Craigslist. Just need to order up the misc fasteners etc. Still lots of cutting and bending to go first.
Decided to increase the tube size since the initial design as I noticed almost every other rotisserie on the market uses 3″ tube. Just need to tweak the bolting set-up slightly to make it easier to set up. Also narrowed things a bit so it will easily fit into a 4′ wide pickup truck bed. When I got the casters – I looked up the manufacturer and they had the CAD model on their site so I stuck those in the model too see see how much clearance I need for them to be able to rotate.
