Scrap box flame licker

[myrickman]

Always wanted one of these engines so I built one from my scrap box(es). The cylinder is an overrun from the foundry I frequent. The flywheels are bronze ~6” gears with tin rims cast onto them. The piston is a cast iron sleeve with a top silver soldered on. The intake valve is a piece of 12 mil shim stock with a 3/8 hole in it sliding in a 14 mil slot. The stack is a ball check to allow any pressure within the cylinder to be relieved and IMO, makes for an easier to run engine. I’ll show the finished product here and then show some of the build photos.

First run without all the pretty bits.

Very Nice.

As the price of materials gets higher, the attractiveness of making things out of scrap-boxium goes up.

I will happily read more posts on projects like this.

Thank You for posting.

That is a very clever set-up. Must remember that if I need to silverrsolder something.

This is poetry in motion pard!!!

I love the simplicity of the valve design, and it’s right up my alley as far as scrap box stuff goes. I love the tin “streamers” coming off your lathe turned flywheels too

Can you explain your ball check idea a bit? Seems like a great add-on for a future flame eater build.

Once again, great engine, thanks for sharing!

The ball check ensures all the pressure in the cylinder is relieved before it need to draw in the flame. When running, you can feel small puffs of hot gas coming from the stack. The ball is 5/16 on a quarter inch hole. A cotter pin limits the travel upward.

I thought it might be something like that, I hadn’t seen one used before and it looked like a great improvement. Is this your original concept?

Thanks again
