A great set-up.

Can't wait to see the final finished product.

I still need to make a proper connection between the boiler outlet and the engines.  I plan to use insulated hard line from the boiler to a port mounted at the base.  The base port will have a connection flange with the same on the engine bases.  I’m researching small disconnect devices to allow quick changes of steam devices.  Fish tank hose is not a great material, but I wanted to try out the boiler.  Need to sketch out some options to decide what would be functional and not objectionable looking.  Always looking for suggestions.

A very nicely turned out boiler , I really like the cap treatment , it looks very handsome & runs those engines effortlessly.

This was my first experience with a boiler.  It seemed much smaller on paper.

I just finished the layout board for my 3” X 6.5” boiler.  The boiler uses 13 fire tubes and heats quickly.  The burner is a home built ceramic unit working nicely at 5psi propane.  The Clarkson vertical engine started this all off when I stubbed my toe on a box of rough castings.  Some of the castings were hard as diamonds, but I used all of them.  Running on steam for the first time, I see a few leaks needing work. The layout bricks are clay mini bricks I thought would look nice and provide insulation between the burner and the base board. I took all the engines off the bookshelf to give them a try.
