A friend of the wife who does a lot of machine embroidery recently purchased plans for a 12" carousel. She has been looking for a mechanism to power it (think music box mechanism?).
Does anyone have any thoughts on where to find such a device?
If it doesn't have to be spring powered I'd think about scrounging around the surplus houses for a line voltage operated "timing motor", they were made in many snail paced rotational speeds. The bearings and shafts in them are strong enough so that you could directly rest a reasonably well balanced lightweight mini carousel right on it.
They used to Be $12 items new, but I guess the transition to electronic timing of everything has turned them into "replacement items" these days, because I just Googled around and some manufacturers are showing list prices above $100 for them now, Shoosh!.
But, H&R has a 10 RPM one which might fill the bill if wifey will accept line powering her carousel:
