"M" Single/Twin

[1hand]

I have a lot of time during the year when I gone on the road working and I can't be in my shop. So I want to use this time away and work on designing a couple marine launch engines. Maybe that way I can stay out of the watering hole at night and stare at my computer to figure out a couple engine designs.....

I ordered plans from Tiny power today for their "M" single and twin. I like that you can just get the cylinder casting kit from them. So my plan is to design the bottom half of the engines and build from bar stock and weld my own engine using their plans as a guide line.

My initial plan is to use their 2 1/2" bore 3" stroke cylinder casting kits for the twin to help cut down on the volume of steam needed from the "M" boiler. Then use their "M" cylinder casting kit for the single, which is 3" bore and 4" stroke.

So with 3 engines and a boiler on my plate now, I should be able to stay busy from now til retirement "15 years yet", and then some

That's a seriously sized engine, are you planning on using it in a boat or for some other (legit) power source? The boiler should be a good build as well.

I haven't really decided yet, maybe a launch. I don't know much about building a boat, but I don't know much about building a engine either......... Lol


I received the prints today. All are drawn full sized, and are really nice.

If you thought the PMR cylinder was big.......check this out

The M is a great engine ....watching with excitement!

They run great in boats...I see them at Lee's mills often.

This is the basic design, but there is 12 total up flow elements, 6 on each side

Looks like a Seabury boiler....or at least similar!

I've seen some like this ....

Keep going!

I think I would like to do the down comers one piece at an angle between the the mud tubes and the bottom of the main drum.

Watch the combustion space below the tubes...you don't want the flames touching tubes before they're done burning...or it just soots up the tubes.
