I’d really appreciate some advice. I’m making a rock tumbler to polish rocks.
Can anyone suggest what motor (and any other electronics / pulleys & cogs) to use to rotate the rock tumbler barrel? The barrel will be something like the one in the link below. It will weigh approx 3kg when full of rocks. The motor will need to run continuously for weeks at a time and hence be capable of doing so and also low power usage!
Thanks in advance for any advice!
