You could be right, Bill. Searched out some photos and it looks very similar. Not much (read none...) progress to report, hopefully get back to it soon.

In the process of trying to figure out what to do next, I checked a few things out with the engine. Figured out a few good things, and found a few not so good things.
I think my next step is to manufacture an axle pump, and either rebuild or replace the hand pump that came with it. Gotta have ways of getting water to the boiler, and I can't afford an injector or steam pump yet.
I think in conjunction with the axle pump, I am going to cast a new smokebox saddle. It looks like the back of the saddle would be a good place to mount the axle pump. It came with a saddle, and I think a fake surround for it, but I can't get things to line up when trying to use them together. I think the saddle may be a later build, not sure. I don't like it, however, it's a boogered together welded assembly, and there is no provision for the exhaust to come up into the smokebox. It also doesn't match either the opening in the bottom of the smokebox, and more importantly, the curvature is wrong.
So, off to pattern making and cast a new one.

And now the bad. I took the steam dome off the boiler. Yeah... Almost wished I didn't, but glad I did at the same time. I would have had to take it off to install a throttle anyways at some point.
The whole steam dome needs replacing. I thought the flange was too thin, and I was right. The base that is welded to the boiler is only about an eighth of an inch thick, and as I suspected, the actual dome looks like it was made from a transport cap for a hundred pound propane tank. Yes, the gentleman that traded it to me tested it to 300 psi, and it probably would hold up for a while, but I think it's asking for failure unless I replace it.
Luckily I have a good lead on a code welder who said he could weld on a new one. I got a chance to look inside and it looks clean, aside from some surface rust. I still suspect that it was never fired. So, there's a project for when I have several hundred bucks to spare. I sure as hell ain't firing it up as-is, which had been my first thought. Oh well, you win some, etc.

as long as the saddle fits around the edges you can always fill the gap with Permatex...nobody but the 4000 people reading Chaski will know the difference after it is painted :shock:

the flange / welding on the boiler looks a bit iffy..but it is probably just surface crud obfuscating the optics.
Too many things going on to bother listing them.

And those tubes appear a bit "carbuncled" indicating deposits from steaming it.
Just my guess.
