Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

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
