Okay - this isn't really a boiler (more of a mock boiler), but I thought it was worth sharing:
I picked up a pressurized sprayer for next to nothing at a garage sale, and turned it into a compressed air supply for model steam engines. I made a stand for it to make it look a bit like a boiler, and rigged up a cam lever to switch the air supply on and off.
Although it will only run an engine for a minute or two, it's a convenient way to show off an engine as it fits readily on a kitchen table, coffee table, or bookshelf.
