Hi Everyone,
About 10 yrs ago I was in need for a small tumbler for Stainless Steel components & used a very low powered geared motor from a Microwave Oven, it must be only about 4W & just plugs into the mains supply. My wife used it continuously for years tumbling stones.
I have made many things from these including being used as the drive motor for a profile cutter etc & you can find hundreds of them at scrap yards for next to nothing.
This is the type I use, they are Japanese & they last forever, see picture below.
I'll probably get my head chewed off for saying this but I see there is a bit of an argument about the mains supply thing again.
It is far better in my opinion to EDUCATE people of any age about mains power dangers instead of ignoring or not answering there questions & try to help them rather than shove them aside.
People will play with mains power & millions all around the globe do it everyday, just look at the internet & you will see this.
You may think that forums such as this is not the place to be playing around with mains power but it is far better to teach rather than to ignore them as they will do it anyway?
What is worse, playing with 900W or buying a 17yr old a 450kW car to drive around in?
Forums such as this with the amount of expertise available should be the place that the inexperienced can turn to with confidence to be able to get an understanding & make things safe to handle.
Look at how many novices play with Valve amplifiers etc without knowing anything.
Professionals teach & there are many here that should do just that instead of being paranoid about something that 3 year olds plug into everyday all around the globe?
