Wal, are you still on 12V ? try a breaker yard for second hand wiper motor they will go all day and you get the gearbox to play with. Not sure on the rpm but I would think that wiper motors will have a fare bit of torque. Hope these help http://www.ebay.co.uk/sch/i.html?_tr...at=0&_from=R40

Wal, I've used a microwave motor in the past for a project. they operate on 240v though and are quiet and about 2 quid. Here's one on ebay with 33RPM speed.

Cool, I may jib down to the local tip for a rummage... Thanks for the heads-up! You too, Longy - wiper motor certainly looks feasible.

Wal how about a small stepper motor. ..Clive

I did think about that, Clive (you might have suggested it in passing a while back) - was worried that they get pretty hot under continuous use, if I ran it off my control box under a new LinuxCNC profile, it would mean leaving my gear powered up unattended, not too keen on that either - call me paranoid..!

Something will turn up!

A microwave motor may work well. If you spin one round and poke your fingers on the terminals you get a reasonable shock, which is quite entertaining.

A cheap (i.e. 2nd hand) drill should also work without requiring much gearing.

Stepper motor are good (ish) when you need to control position, but for spinning things in general you're better off with other motor types as they're a lot more efficient and simpler to drive, so should be cheaper.
