I was able to find some motors that I had somewhere. 2 9v DC motors salvaged from a printer was rigged to a plastic gearbox that have 48:1 reduction gears. The output wheel now spins slowly enough to serve as a rod dryer. The torque is also quite solid. I now have to figure out how to connect the rod butt to it somehow, like a chuck. I will have to figure out how to make the other motor work as I don't have a gear box for it.

I also have a motor salvaged from a microwave. The motor for the turntable spins at 3rpm with 120v AC. Unfortunately I messed it up to the point it can't be used. It is a induction motor and it gets hot when it runs for some time. Probably a gel ice pack resting on it can help reduce the temperature.

For many years I used a tuna fish can cobbled onto the shaft with 4 screws through the can wall at 0, 90,180,270 degrees with rubber bands stretched between the opposite screws. Sticking the butt through the junction of the rubber bands held it securely.

I built a rod drier from a bbq spit motor over 30 years ago. 3 RPM and never had a sag.
