Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Hello fellow steamers , I am trying to find a very small steam engine for a project and looking for suggestions please ,I'm looking for a quality made engine 3" long or less and not more than 2" tall, please don't suggest any Chinese engines as I won't consider them. Thanks for any helpful advice you can give.

Do you have any of Ben Peaks engines?

No...I'd forgotten about him (hence this post) A good idea Tommy , but I don't see them for sale very often.

Do you need a single action or a double action or doesn't it matter?

I don't think it matters , the load will be very light, would like it to be smooth at low rpm/pressure ( A tough order for a small engine) thought about Saito , but all I've seen of them was to large.

Bonjour Bruce,
JMC makes nice 1 cm3 Stephenson bicylinders : https://www.jmc-vapeur.fr/
 

Thanks Arnold, the size & style is close to what I'm looking for.

Bruce, don't you have one in the top of your cane? Have you ever made one?
Or how about one of these from Wilesco?

Here's an idea for you Bruce. Take the engine from a Jensen 70 or similar, make it horizontal
and low. Replace the spoked flywheel with a small thick marine style wheel. That'll keep the
height and length down. Should run with that mass spinning.

Good ideas all , I've considered the D2...not quite what I'mooking for, I would like a miniature Creters looking engine, I went in my mind all the Jensen  variations and a #35 seems like I "may" be able to make compact enough. Still looking for the right engine. I really prefer a slide valve horizontal engine.I think Nick bought a miniature Stuart from George Brittnel that would do nicely 😉😄👍
