small air compressor for powering steam model

The little aldi or halfords tyre inflator devices may do ........

noisy little buggers ...

but

if you open one up ...inside there is a nice alloy die cast pump...........very olde worlde looking....., piston ...cylinder and external crank.

now with a bit of dreaming and thinking ............

you could hook it up to a variable 12 volt transformer ..........hornby etc

and have it running slower ..making less noise...............and looking the part.

all the best..mark

paint the nylon gear black ..add a motor and variable transformer of your choice .......put it in a triangular frame..and you may have something that is more of a talking point than lady Stephanie

It might have been an airbrush compressor.

I would avoid Moebius oil as I believ the formulation must have been changed recently. I, and other clock makers, have found the oiled to have gelled within a couple of years thus causing clocks to stop. When checking my bottles of oil, both had thrown a sediment. I now use a synthetic motor oil for clocks.

-Or an aquarium aerator pump?

I don't believe these pumps can deliver any useful pressure. They only need to over come a foot or so of water in normal use.

I use the oil sold as a laxative by drug stores (chemists). It works for watches and clocks too. Light oil for the going train etc. Heavy oil for the escapement. These same oils are also sold as white oil for lubricating restaurant equipment, electric shavers, and some brands of clock oil.

Not enough output!

CO2 cartridge?

It'd be quiet...

What SAE ?

Is that what's known as 'liquid paraffin' ?

I wish I'd paid more attention at the time, but I didn't think of using it to power the Lady until I got home (my original intention was to drive the flywheel rim from a rubber wheel on a 12v motor).

Ho hum - I'll just have to keep attending exhibitions until I see it again (good excuse to use on 'her indoors'...)

I'll try re-posting this query on the modeleng-list - my apologies to those who've already read it here.

I would use first class post for a good Stamped Addressed Envelope

More likely Castor Oil ?

-adrian

Do you mean '5W' ? if so, where do I get it - I've never seen any less than 15W (universal tractor oil).

Also, what brand would you recommend ?

TIA

ISTR reading that WW1 pilots had frequent underwear-incidents due to the total-loss castor-oil based lubrication system of early rotary engines.
