WELCOME
TO DEAN'S MACHINES
This page will feature
small steam engines and related topics.
A short description
will accompany each engine.
All of the
machines on this site
are made in my small machine shop.
Soon there will be
items for sale,
either as completed engines,
or as materials kits
with plans.
This
little engine has a 1/4" bore and a 3/8" stroke.
It
will run on steam or air.
The
air supply I use is a small bicycle pump
The
Flywheel is of brass, cylinder and pivot block of steel
and
the base, piston and crank disc are made of aluminum.
This
is a common design, and there are dozens (maybe hundreds)
of
variations of this style. I made this one in about six or seven
hours
after seeing a picture of one somewhere.
At
10 lbs of air pressure the moving parts are a blur.
This
engine has a stroke of 3/4 " and bore of 1/2 "It will also run on steam
or air.
The
Flywheel is 2 1/2 " so it will run fairly slowly. It took about fifteen
hours
of
my spare time to build. The crank is built up from drill rod and
the throws are
brass.
The main bearings are brass as are the con-rod and rod bearing.
The
piston and the valve are made of aluminum. The flywheel is steel.
This
engine is of my own design, although all of the operating principals have
been
in use for over a hundred years.This is a single acting engine,
which
means it has one power stroke perrevolution, similar to a
two
stroke gas engine.
How about something
different?
This
is a twin cylinder oscillating engine.
It
has a 1/2" bore and 3/4" stroke.
This
is a double acting engine. This means that
for
every revolution of the crankshaft, each piston has
two
power impulses. One as steam (or air) pushes down
on
the top of the piston, toward the bottom of the stroke
and
another as steam pushes the piston back up to the top
of
the stroke. So, for this engine there are four power
strokes
per revolution. I have run it on steam and air.
For
air power I use aquarium pumps, one for each cylinder.
