Hi all:
I am trying to locate the origin and drawings if possible of a Twin
compound steam engine that I have just acquired, it needs a lot of work.
The engine stands about 12" high 10" long, the cylinder block is cast
iron, the high pressure cylinder is 1 3/8" Dia, low pressure 2 1/4" Dia,
Friends,
This is a request for information directed to our British cousins, although
I'll gladly accept a response from anyone who knows the answer.
I'm reading the chapter on Cylinder Design and Construction in my copy of
the K.N. Harris book "Model Stationary and Marine Steam Engines." In

when i pumped the phrase "tracks ahead" into google the other day, it
brought me to the "tracks ahead home page," which seems to have been

Gordon Watson did a clinic at Diamondhead some years ago on fabricating
cylinders from round bar stock, connected by a "steam chest" of rectangular
bar stock into which ports had been drilled. He silver-soldered it all together -

Litharge and glycerin were the constituents of what was a predecessor to
2-part epoxy. Properly mixed and applied, the combination cured to become a

Before they changes the pictures and paper, a dollar bill made a good gasket
material for live steamers. I've seen Jerry Reshew and both of the Quirk
Bros. use it.

answers from England was this one from Colin B, whom I have found to be most
helpful:

Hello Casey and Everyone,
I'm really going to step out on a limb here since I don't think that I fully
understand your predicament.
Yamaha (the Japanese motorscooter manufacturer) makes a product called
"Yamabond". It's basically an "instant-gasket" type product but is much thinner

It has been around the circuit several times, I believe. Series are
distributed with a finite amount of rights (years and/or broadcasts) and
