It is a 2 1/2 x 2 1/2 twin high. Ideal engine for a 20 foot boat and very well designed. If you're thinking of building an engine, you should consider this one.

Jack, Simon,
Nice work all around. From what I can see so far, that little twin will be an excellent small launch engine. The twin in the tug has performed flawlessly all last season, I just pulled it on Friday to make some additions, it's still in great shape, there is one eccentric that needs to be adjusted, but everything else is still very tight . I like it so much, I'm even going to set the timing on it
Smooth power and easy starting and easy running all the way down to 5 psi. Twins are very easy to get a long with.
Like the little boring mill too. Looks like a handy machine to have. Perfect size for machining these small castings.
Oh, a safety note. I would be careful wearing sleeves (or gloves) around machine tools, very dangerous.

Hi Simon,
Great vid, the engine looks very smart indeed- you just need to get a Frolic and away you go......!
Interesting that you have chosen to incorporate a large diameter flywheel- is this because of the lack of crankshaft balance weights?
Hope your keeping well by the way.

Greg,
This engine is a replacement for my boat “Grayling” I found it in a very sorry state and have redesigned it and rebuilt it using my standard component designs, e.g. double bar links, extended conn rods, glacier DU top end bushes running on hardened pins, conical top pistons, balanced slide valves etc.
It's not quite finished yet the crank-pin bearings need to be adjusted hence the slight knock.
Regards
Jack

Ah, this the one! It's going to look lovely in Grayling. Are you still going to run through a condenser with the twin?

Greg,
I gave up with condensers many years ago, puffing is so much simpler and helps the fire. Hopefully the extra exhaust from the twin will compensate for the extra steam required, also there is an exhaust feed heater built on to this engine.
Regarding your question about the flywheel, no it happened to be lying around and is useful for setting the valves up. I may retain it though due to my tooth belt drive which can make the engine knock when reducing speed. I don't bother with balance weight on engines of this size.
regards
Jack
