Deluxe Swingarm - Böhm Stirling engine (BHB9)

Deluxe Swingarm - a fascinating machine, which directs the energy flow upwards and produces a surprising amount of power.

This very well made German Stirling runs using the supplied burner. Just add methylated spirits (denatured alcohol), light and place under the Stirling engine. Wait a short while for engine to heat up and give the flywheel a flick. It will burst into life and get up to an impressive speed. You can then throttle the speed by sliding back the burner or removing.
