I build working scale models of antique hit and miss engines.

Not really a scale model of any particular engine. I got the plans off the internet, and have been building it at work during my free time.

Almost done!

Pretty soon we'll try to start it for the first time.

I'm currently building a little boiler to run some of my scale model steam engines.
Almost done with the boiler itself. Now I am making a whistle for it.

Took measurements from a full sized steam whistle, drew it up on Autocad.
Now I need to scale it down and make drawings. Then the fun begins!

I'm currently building a scale model of a Ryder Ericsson stirling engine.

Here's where I'm at right now.

Quoted from cottonm4:

Looks very good. Are your legs and base castings you made? What kind of tools do you use?

Thank you!

un-machined castings are available from this guy: https://www.myersengines.com/engines/rider-ericsson.htm

There is a surprising amount of stuff like this out there!

Cabinfeverexpo.com Is worth a visit if you are into that sort of thing.

I use a lathe and milling machine to build my engines.

Since you asked, here are the machines I use primarily.
My job being a prototype / R+D machinist, I get to do small jobs for myself when I can fit them in.

One of the perks of being a machinist, I guess!

Got some of the displacer linkage finished and made some scale 4-40 bolts today.
Nothing sets off a little engine like scale hardware!

Today I finished the displacer piston and associated hardware.
Also finished scale nuts and studs for cylinder flange.
Now I need to get the cylinder honed before I make the power piston.

Almost done!

Quoted from cottonm4:

I see your glasses in the back of the pic.
Throw down a dollar bill for size relationship. Please.

It's at work, and I'm home for the weekend!

I would say it's about 8" high and 5" long.

The engine is pretty much complete now. I finished up all of the plumbing. Got some of the bugs out, and it runs perfectly.
I have to make a burner yet, and a skid to mount it on. Then paint and final assembly!

Sorry for the crappy video.

Quoted from Viggin900:

".... Do you have any plans for it to do any work?"

It can run the little pump for the cooling water, but not really anything else.
Stirling engines have virtually no power, and are difficult to govern the speed.
There is a reason that you don't see them in use nowadays.

The big ones are rare, expensive and difficult to move around.

no....it's more of a curiosity than anything else.

My father-in-law left me this cool little engine. It is new in the box, and has never been run.
I always loved these, and never thought that one would come my way some day!

A coat of paint and a little tweaking, and I'm all done!
