Free plans. Build Model Stirling Hot Air Engines.

Stirling engines, which are actually hot air engines, are great engines to make working models from. The hot air engine was an early invention in the 1800s, and looked verty promisimng as a source of power for all kinds of projects. However the low power to weight ratio of these engines makes them most suitable for stationary power rather than for use in vehicles of any kind. That being said several hot air engine powered large ships were built in the 1800s and they worked very well. Hot air engines are of course run by hot air which is heated from a heat source such as coal or wood burning, as it was in these ships.

Model small scale Stirling engines are usually powered by an alcohol flame or even by a candle flame.

We have free plans for hot air engines which you can download at our website, and we also have a free plan for a rather unique candle powered engine. This amazing little engine gets its power solely from a candle flame. This is a simple to build vintage project and runs really well.

When you build model hot air engines the key to success is to get all the moving parts air tight, but as friction free as possible. The engine will then run perfectly. If there is a significant air leak it will not run, and if there is too much friction it will run poorly if at all.

Go to our website and download the free PDF plans for these and many other vintage projects.
