Re: Heat transfer on the shaft
If you want direct drive, you could create an aluminum coupler with heat sink fins to connect the motor to the rotating shaft. Phenolic or some other non-metal would work as well.

I researched a bunch of these when I was getting ready to start my build. One guy said he overheated the plastic gears in his motor; that and timing the release of the shell to the tray were the reasons I went with a chain drive.
have you found a good source for small sprockets and gears?

Ever think about using the motor and works from an old can opener?
