I found the owners manual for my Hobby Zone M1A1 Abrams Tank. They list replacement gearbox and motors for this unit. Tank # HBZ2050 or HBZ2051. 360 degree gearbox: HBZ2066 lists at $7.49 and they have a picture of it. But you would have to make the cogged part on the turntable that this unit would engage. Find this with pictures at www.horizonhobby.com
I know someone who uses old battery powered screwdrivers. He takes the motor and either adds a rectifier or uses a DC power pack as his power source. The motors have good torque and are slow moving and can easily geared down.
I use a dc geared motor, that spins a threaded rod, hooked to ann arm under the turntable. Bought it on Ebay @ …DC Geared Motors… Very high tourque and slow revolution…Tim
Find an old discarded microwave.Their motors work off 110volt and run very slow.I’ve already rounded up a few for my layout in the works.
Correct me if I’m wrong, but could that microwave mechanism have a bit of radiation exposure???
Steal the Geneva gear system from an Atlas HO turntable. It is nicely indexed, runs off a low torque motor and is fairly inexpensive. Check the back room at Scale Model, I thought I saw one there.
The Axeman used to have bbq rotisserie with good gearing and low speed, but that was a while ago.
Another option is a simple worm drive.
Boyd, electromagnetic radiation is everything from power-line frequencies through the radio spectrum, through light, x-rays, and on to gamma rays, or, as we say, DC to daylight. Every photon, or quantum of radiation, has an energy that is proportional to its frequency. The energy of photons up to the frequency of visible light is pretty benign. Starting with ultraviolet light and going through x-rays and gamma rays is where they cause damage. So the parts of a microwave oven are not to be feared–they are not radioactive. And whether the food is to be feared depends only on how good a cook you are!
