Cycle Engine Plans |

"Vintage" is a 90 degree engine
with a horizontal displacer
cylinder and a vertical power
cylinder. Connecting rods for
both cylinders us a single crank
pin. This makes for easy
construction and interesting rod
motion. The engine frame (blue)
is made from aluminum plate,
most of the rest of the engine
is machined from brass or
stainless steel bar stock. Most
of the brass parts were nickel
plated, but that is not needed
in any way - just cosmetics to
suit me!
Vintage makes a perfect power
source for the Miser engine. As
such, it is water cooled and a
belt powered water pump
circulates the warm water
through a ring that Miser sits
on and back through the engine
again. This powers the Miser
while the Miser becomes the
cooling "radiator" for Vintage!
Just about any other simple
radiator can be used such as a
10 foot loop of vinyl aquarium
air line tubing, etc!
The plans include the entire
engine as shown, but with a more
appropriate water pump design
than the one I used, a heater
ring to operate a Miser engine
and an alcohol burner (not
shown). The sole exception is a
straight spoke flywheel machined
from solid which is similar to
the one on the "Vickie",
"4-In-1" or "Beamer" engines. An
optional curved spoke zinc alloy
flywheel casting shown on the
above engine photos is available
below from time to time.
Vintage runs very easily on a
tiny 1/4" diameter by 1/4" high
alcohol or propane gas flame.
The

sheets of drawings and 2
