Let's Build a Can Stirling Engine
The Can Stirling engine can rotate using a candle as the heat source. This engine is constructed with very
simple materials. There are a can, a balloon, a wood board and others.

He is teacher of Kasukabe technical high scool.)
Step 1 - Material Preparation and Structure
To make the Can Stirling engine you require these materials: wood board 10mm thick; balsa wood 10mm
thick; wire diameter; fishing thread; a balloon; square lumber 5mm square; two thumbtacks; a
paper clip; clay; a 200ml steel can; cardboard; a candle; nails (or wood screws); and rubber bands.
These tools are required: cutting pliers; scissors: a saw: wood glue: some quick-drying glue: and machine
oil.
This engine has a very simple structure as illustrated. It makes use of wood frames, a wire crank shaft, a
can cylinder, a rubber balloon diaphragm. You can get these materials easily. The wood piston is
connected to the crankshaft with fishing thread.

Step 2 - Cut a Wood Board
As illustrated in the following figure, you must make two side boards, two boards to fix to the can, and a
bottom board, all of 10mm thickness.
You must make the holes for the crank somewhat bigger to reduce friction.
