Low Temperature Stirling Engine
Both
engines were scratch built from drawings and parts purchased from Jerry
Howell.
The larger engine has a 5"
dia. flywheel with .600" bore x 5/8" stroke. At shows I run this
one on two or three HotHandS-2
hand warmers.
The
smaller engine, being half scale, has a 2.5" dia. flywheel with .300"
bore x 5/16"
stroke. This engine is
a lot more of a challenge to build, what with the 0-80 and 00-90
screws. With tired eyes, I need tweesers and maginfier glasses to
put it together.
Both engines have stainless steel
cylinders and crosshead guides with pistons and displacer rod bushings
machined from graphite. Flywheel, column, and displacer plates are
machined from aluminum. The displacers are machined from
polystyrene foam.
