This is a photo of the core for the bottom part of the boiler.



This is a photo of the core for the water tank.(looking at the bottom) with styrene on the top and sides.

Very interesting.

You don't experience any problems over time with difference of expansion between the wood and styrene due to humidity...or shrinkage from drying?

    If fully sealed by glued with a styrene top and bottom it should not give problems, unless very high temperatures  expands the moisture inside.

Very nice wood work, Gordon! 
Starting with such a solid foundation sure makes life a lot easier.

EDIT:  I posted this based on the photos on Page 3, then
went back and saw the boiler on Page 2:

Holy Smokes, Gordon - that's insane!!!!

Marc, I don't know if this will be a problem or not. I have other tanks with the solid wood core that are four or five years old and I can't see any problem with them. The tanks on  my Michigan California Shay Are almost forty years old and I can see no problem with them. So only time will tell. I do live in a very dry place and maybe this helps.

I've laminated styrene to wood cores with no long-term issues,
and we can get pretty humid here in New Jersey. 
Such small pieces of wood shouldn't create any problems.

I have got the boiler and water tank ready for paint. Here are two photos.

When you start building, Gordon, you don't mess around! -- Russ

  Now I understand why rivets are in short supply in the hobbyshops........................

  I don't spend more words on it... save my superlatives for the end

You never post a picture that isn't worth being thoroughly studied, Gordon. Some for the ideas they contain, some simply for the pleasure.

[Ken Hamilton]

It's really good to see these pieces before paint, to study & appreciate
the different materials used in construction.  Thanks, Gordon.

Wow this is awesome!!  Just one question is the word "sleep" in your vocabulary!!  Hell its on;y taken a week to get this far most of us would still be doing rivets.

Not me!  I would still be on the floor looking for the rivits that flicked off.
