Much thanx for the info, Bill. Now, the next question is . . .
. . . actually several questions.
1. Is there a commercial source for small quantities of litharge? As in,
is there a trade name for this stuff?
My "google" search turned up a commercial outlet in India but no US branches
or outlets. Many more items that appeared in "google" point to the extreme
health hazards of this stuff, making me wonder it its worth using. That
leads to the next question.
2. Is there some other goo stuff out there in the market that might more
conveniently/safely be used when fabricating cylinders with separate port
faces?
If there is no goo available, I imagine that I could prepare steam tight
gaskets from thin copper. I've used copper gaskets with good results on
other projects. I just have to remember to anneal the gasket before
re-using it.
3. Has anybody out there tried fabricating cylinders using separate port
faces? If so, how were the laminated pieces kept steam tight?
Maybe I could cut gaskets from some sheet of composition something or other
used in IC engines, something that I could get at Pep Boys or Trak Auto?
Trouble with this (and with the copper gasket idea) is the close tolerances
needed to make a reasonably sized model cylinder. I'm thinking steam ports
about 1/16" wide with a 1/16" wide land between the steam ports and the
exhaust port for a cylinder of 1/2" - 5/8" bore. Thats mighty fine fitting
for a gasket made using hand tools, like an X-Acto knife. I'd really prefer
smearing on some goo when fixing the port face to the cylinder.
