Turret Supplies?
 

I'm inquiring about various sources of parts to build a turret. I'm talking about large gears, turntable bearings, and maybe light/cheap slewing rings. We are considering using an automatic transmission flywheel, but it's rather heavy and we don't know the pitch of the gears. Does anyone know of a source for aluminum automatic transmission flywheels and their pitch?

Turntable bearings? Come on, ghettify! Put a couple casters on a disc and put them in a raceway on your robot. Then put a torus above it with casters mounted on it. It may be heavy but it'd win the ghetto (er... low budget) engineering contest. (FIRST should have one)

Home Depot sells some really cool turntable bearings that are used for lazy susan style cabinets. Just go to the cabinets are and ask someone.
