here is a quick video of what i want to do
but i just dont know how to get the ball to rotate slowly like that, where can i find a low RPM small electric motor that can rotate up to 16lbs?
everything else i can do fine but im just stuck on this
Um really? Grab a power wheels motor. Another good source of a motor would probably be an old seiling fan, or old broken microwave (with the rotating plate thingy. I would recomend some type of reduction drive. even if its just a simple belt. As far as speed you can always use a dimer switch. kind of rudementary but it works.
Hah nice Jeff, I still use the baking sheet/oven method
