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

  Thanks Bruce, that is a great list.
If I'm in a pinch I can use it to pick
my poison.

 As an occasional lapidary I have plenty
of experience with abrasive pastes for
shaping, for the most part, hard agates
and rutilated quartz.  Grits from 240
to 100,000, anyone?

  I have yet to try anything other than
the injection of steam oil into the valve.
I'll test that tonight.  I could also
tighten the spring a bit like I did in the
S/V.  I'd like to put off disassembling
the valve as it appears to be neccessary
to file the bottom of the shaft first.
That is a permanent change and a last resort
in my book.

Thanks,
Wayne
