Nitrile O-ring belt drive - suggested stretch percentage..?

[longy]

Find an old tumble dryer that has a plastic drum complete with motor. Or just use one motor and a long belt around your tub, like the TD does. Cut a couple of rings out of some ply to fit round the tub glued and screwed to stop the belt from coming off. Simple and cheap just like me LOL
Just read eddy's and he's thinking along the same lines as me.

The reason has been stated before:

Wal: I didn't want to get into bigger motor territory - 12v small and quiet(ish) was the aim!

Possibly not to get into 230V territory ..Clive

Well that's true but it may be that Wal does not feel confident working with 230v or he may not want to be hassled with the associated control gear for a larger 230v motor ?
That's why I suggested the tumble dryer, it's just a plug and play device, the motor is quite small, it's quiet

Some where i've got a 12/24Vdc motor with geabox that would do this but not sure how fast it spins. I'll check it out and if it's fast enough your welcome to it just pay carriage.

Nice one Dean. No mad rush, drop us a line when you find it..!

Hi Eddy,

Yeah, the main reason I'd like to stick to 12VDC is that it's compact and straightforward. Out of interest I had a look at some dryer motors on ebay, this seems like a decent, cheap example:

Hotpoibt Vtd Indesit Creda Series Tumble Dryer Motor | eBay

...and as luck would have it, here's a vid of what appears to be a very similar motor in action:



You can see that it would require a fair bit of gearing to get it down to 30RPM - there goes the compact and straightforward..!

With my approach, I'm a gnat's chuff away from something that I'd really be quite pleased with - if I could just find a 12VDC 30RPM motor with a torque rating of 300Ncm... Hey, I'd even try a compact 240AC... Something along these lines would be great:

High Torque AC 220V 30RPM Gear-Box Electric Synchronous Gear Motor Replacement | eBay

if only it had 4 times the torque...

As ever, thanks to all for your input!

Wal.

Hehe... Hard to call that one, Clive - you're comparing gasses with solids...

EDIT - Actually you're not - never mind arse/elbow, I think I've mixed my chuffs up...

Deffo catch up one of these weekends - hope all's well your way.
