The boiler for the RMI Prairie 2-6-2 locomotive that I am presently building was built by Wasatch Railroad Contractors in Cheyenne, WY. The pictures below are from the Wasatch web site and were taken during contruction of my boiler.
There is quite a bit of work in building a boiler, even  miniature ones, such as the types used in our hobby. They must be built to safely handle the heat, pressure and vibration that occur naturally in the running of a steam locomotive and take into account that some times things are not 100% perfect while still operating in a safe manner.
Here are some photos of my boiler being built at the Wasatch facility.

A close up of the required boiler data and associated ASME S-Stamp making sure that it was fully inspected and passed all of it's tests.
Tim and I lifted this boiler out of his truck and it was extremely heavy. As my forklift was not available we could not lift it completely and had to pivot it to the ground. I would estimate that it weighs in at over 350 lbs.
After seeing all of the work that goes into even a small boiler, I think it is a project best left to the pros.
The boiler has a diameter of 10 3/4" and it is approximately 49 inches long. There are 34 flues or boiler pipes. The throttle valve is located internally in the dry stand pipe. This boiler will be heated using an atomized oil burner.
And that is all there is to it. Big smile 
Nice job Wasatch, can't wait to get it into operation.

I used to be a rocket scientist, now I am just a space cadet.
You only need three tools in life - WD-40, Duct Tape, and a Hammer. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape. If you can't fix it with a hammer, you've got an electrical problem.
