different shape for the boiler or steam chamber
- Hello, group. I just made put-put number 15 and this time made the
shape of the aluminum boiler different with results which I like very
much; the boat moved and sounded much better. Pictures and notes near
the bottom of my first boat page:

making it narrow at the bottom, to "just fit" the boat floor, and
wider at the top, sealed end.
