Vance and all:
You can find both of the Bridgewaters' books; "more" is listed from several
sources in the 21-25$US range on:

I often do better than Amazon using this book search source (and it
includes Amazon listings as well).

Bob, good news and bad news: The good news is that the Levy book (the one I have) is
readily available used for under $10. The bad news is that the Bridgewater book is
readily available used for around $60, and the second volume ("More...") fetches about
$100.

delightful book, but I never did build any of the mechanisms. This is a great
book if you ever decide to do any Automata sculptures. The othe
Vance,
That might be a nice item for The Naples Depot to have on display. It would
be even better than a diagram because it would give a "hands-on" item for
the visitors. Keep me in mind if you decide to go ahead with the project.
Something about 12" x 18" would be good for public display and use.

Bob, I tried to find them online, too, without success. If you happen upon the titles,
maybe we'll track one down one of these days.

There are two books published by Dover books that has designs of mechanisms

I have been thinking lately that it would be cool to design one of those hand-cranked
valve gear models to laser-cut from wood. Is that something that would interest anyone
else?

I'm aware of that but whatever the actual origin we still call it by
the name Stephenson and everyone
Thanks for piping up, Keith. Your recommendation to make a moving model
from a book diagram is great one! And not at all confusing. I will do it
this coming weekend and will make it BIG so I can see it. The samples of
valve gear simulation graphic software that I have seen are commendable

Stephenson valve gear.
This is not quite correct. the original Stephenson valve gear consisted
of a loose eccentric and a driving collar and driving pin. The
"Stephenson" valve gear as we are referring to came about in 1842 when
a Draughtsman named Williams Employed

Both the Accucraft and Roundhouse valve gears are a single

expansive working possible, notching up only shortens the valve travel and

At the National Summer Steamup Jeff Williams was kind enough to let me
inspect the valve gear on his C-16. I had a question about why prototype
Stephenson valve gear had two eccentrics per cylinder that each drove
one end of the expansion link. The C-16 has only one eccentric per cylinder
