An engine that can be built without a lathe

This amazingly Green Hot Air Engine runs on the most common heat source know to man – the Sun

A solar powered engine has been the goal for many inventors who have strived to improve the power to weight ratio
so that the engine can be used in a broad range of applications.

This great science project has ample power to drive a small model pump or turn a small fan for display purposes.

Driven by the heat from the Sun, this engine could with a bit of “spin” be called a Zero Emissions Thermo Nuclear Sterling Engine

At night, the engine can be removed from the solar reflector and powered by good old fossil fuels or any convenient heat source.

Equipment needed for building this Hot Air Engine are the usaul home workshop tools and equipment and the use of a Mini-Lathe
and Drill Press

Once the flame is lit, this charming hot air engine heats up for action in less than a minute.

The Hot Air Engine, or Stirling Engine is now back on the desks of researchers and scientists

due to the engines almost unique ability to run on any heat source.

Many free engergy sources can be used to heat this type of engine, such as hot springs, solar power and even ice and snow.

In this easy to make model Stirling Engine, the heat source fueled by alcohol.

The engine if built to the specifications given, is capable of driving small models, pumping water or turning a fan.

The Hot Air Engine does not require castings, but does require some turning on a mini-lathe and the use of a drill-press.

The usual home workshop tools and equipment are required to make this model Hot Air Sterling Engine and is free to download

In his patent of 1784, James Watt made improvements to the steam engine
One of his improvements was the parallel link motion, and this model replicates this function.
The piston is driven vertically up and down in the cylinder by regulated steam from the boiler.

The vertical motion is converted by the walking beam to radial motion at the crankshaft.

The valve that controls the direction of the steam in the Double Action Cylinder is controlled by an eccentric mounted on
the crankshaft.

This is a marvelous project for the modell engineer and is a very visual steam engine.

The rocking motion of the beam and valve rods and the steady rotation of the flywheel will captivate onlookers.

The use of a mini-lathe is advised, along with a drill-press and the usual home workshop equipment and tools.

The Flywheel is best turned on a full sized lathe due to its size.

This is a great first project – the plans are clear and well dimensioned, the project does not require brazing or silver solder and the engine works well.
