Gunna jack ya thread for a couple of pics Hendo,
Here's ours in action at Outback Challenge in 06
Made from 2 star droppers with bits of 4mm thick angle welded in 5 spots, it uses the gears off a 12 speed mountain bike we bought from a garage sale for $10, and that is turned by a Datsun 180B wiper motor with a 2 amp fuse in it we then stuck a bit of galv plate near the motor to shield it from heat.
It has a boned out pork forquarter on it that has been wrapped completely with the skin to get 360 degree crackling!...it works a treat and never even made the battery disconnect on the car it was running on after 3 1/2 hrs, we even put a 21kg full lamb on it and it still turnd with no drama's...its a trooper!
