Very interesting offer. Hmmm.
I have an engine/boiler combo made
in 1926. I has been working but there is
a serious design flaw - the steam valve
chest is blind. You have to set the valve/rod in
the chest and then put it on the engine and
hope you set it right. But, the rod and
keeper-nut are just barely usable (victims of
mineral corrosion) and could fail at any time.
Fortunately, Ive been lucky so far.
So, if it fails again (every time I run it could,
realistically, be the last - as when I got it) it
will be in the valve shoe/rod join. This time
I would think milling the top of the steamchest
down until it opens up and replacing the amount
milled off with a like brass plate would do it. Or,
make a whole new steamchest/detachable cover
exactly the same size. In fact, that would be
preferable. Is this possible? Seems pretty vanilla
in comparison to some of the work I've seen done.
I added a photo of the disassembled steamchest.
and the engine as it is now - a runner.
Stay well,
Wayne
