The MM-K Stirling engine kit is a ready to assemble engine that will run on the heat of your hand. We also sell a ready to run Stirling engine that will run on the heat of your hand.

MM-K Stirling Engine Kit

The kit arrives in a custom foam insert. This ensures that all the parts are safe and secure while in transit. It also doubles as an assembly aid, holding the engine still during assembly.

The PDF instructions provide a detailed step by step process for building your MM-K Stirling engine. The instructions include high-quality images showing the complete assembly process along with full parts list and detailed written instructions. Assembly should take no more than 30 minutes. All you need is a small philips screwdrive (the Pozidrive brand is good) and a small flat head screwdriver.
