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.
I like this more all the time Tommy , I have all the parts 🙃👍


Yes you do Bruce. You have the parts, the tools and know how. With your lathe and a hunk
of brass bar stock, you can make the flywheel to fit and look anyway you like.
With the way you like to improve upon things, I can see it now. Real bearings, everything
polished up, painted and shiny. Just do it! ;)

I really like the Bengs engine Arnold presented, and would buy a ready to run model. Still looking...

Re::you are aware that an engine with a .9" flywheel would need to be pretty will seasoned to run"
I am aware.
My project would not do justice to a wonderfully presented rendition of a miniature model steam engine such as Georges 😔

Bruce, here is another one that might fit the bill.

Built by George Britnell. Maybe you could talk him out of it?

George's engine would be lovely (all his creations are) but it appears to be high revving with a very high stall.
Keep in mind that George's engine is fairly new at this filming and not likely broken in yet. A good break-in and a small work load would likely allow for slower running. That said, you are aware that an engine with a .9" flywheel would need to be pretty will seasoned to run slowly.

Are we going to see a miniature SPS popcorn wagon??  ;D  ;D
I had the same thought!
well no ,not a Popcorn wagon (yet) I was afraid I might have led some of you to that thought when I mentioned what type of small engine I was seeking.
here is a picture of the project so I can dispel some of the speculation out there  ;)

Hi Bruce, Gage GA Graham Industries had a horizontal that is the only one I am aware of that could be used as a Cretors small enough to fit within your size requirements.

unfortunately, Graham Ind. is out of business.

Thanks Arnold,  I do like it ,I wonder if they sell one ready to run ?

I guess they are only available as a kit - the website
from Bengs in english language:

Bruce, how about this one from Bengs:
This "Danni" looks maybe closer to a Cretors
bore is 15 mm and stroke 18 mm
dia of the flywheel 80 mm - but you can also
make a solid one with 40 mm.
the set is milled all other materials raw.

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 😉😄👍

Maybe even a Jensen 85 or 5? I,m sure you could adapt it to your need.the little Bona of I bought from you at cabin fever a few years back might work too bad I won,t part with it :)

It is too bad that Graham Industries stopped making engines.  The HM1 might be a good choice if you can find one.

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?

Bruce - the small motors I know are from AULD NZ.
They are easy to remove from the base. The size is
about 2" x 1,25" and they cost around us$ 50.00 to 70.00
(ebay)
Have a nice day, Arnold

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.

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.
