Thermoforming the Acrylic Sidewall for an LTD Stirling Engine
http://StirlingBuilder.com - One of the bigger challenges with making a round Stirling engine is making the sidewall for the pressure chamber. The ideal material will be transparent, and will be a good thermal insulator. In this video I will show you how I use a heat gun and a jig to thermoform the acrylic sidewall for a round Stirling engine.
