ne day
while driving in the country I discovered an old steam engine in front of
a house and upon inquiring I found out it was a sawmill engine, circa
1890. Further investigation revealed that it was designed and
constructed in a local foundry/machine shop here on this island, known for their
manufacture of starch factory boilers and equipment. I thought it
would make a nice subject for a model, so when I got home I made a drawing of
the engine from memory - I was surprised later to find how close it comes to the
original.
I
took a few shots around my model plant recently...
The
boiler is a Horizontal Return Tube type.
Condensate and
feedwater tanks are visible from this view.
Here is early
shot of the model, still bearing a temporary "S" on the valve chest.
The old
engine began appeal to me. After many visits back to the prototype, I
was able to get precise measurements and pictures. I fabricated the
engine and then made a wood fired boiler and other fittings which I eventually
mounted together as a complete steam plant.
Unfortunately, I
didn't finish up a couple of small engine parts yet.
Lighting was very low in this back corner -
so depth
of field was a problem in this shot below.
I made a pencil rubbing
of the etched nameplateplate on the original engine.
I electronically reduced
the image in size to suit the model.
These are the blowdown
valves at the back of the boiler.

No
fosil fuels in that firebox!
That's Norway
Maple in there!
A bit of creosote in
evidence, but what a delectable maple aroma this boiler has acquired!

spring-type safety valve in this picture below.
This shows the back
tubeplate with hollow stays.
Some silver brazed boiler tubes
show in this flash picture.
I have been asked about the boiler setting and brickwork. Click Here for more.
Dirty old boiler!
And just for a
change of century.....
Here's one of
my earliest efforts - a model gas-fired boiler atop my stainless steel coffee
cup.
Both the model Cleaver Brooks CBH-70 and the sawmill boiler have 3"
shell diameters.
