Stirling Engine Alpha Monochannel

Please read full description below!
This is the second run of my engine that was
made to test some solutions,
This is not the production engine.

Obviously it is not very efficient engine but simple enough
as I made it for one week (without drawings).

Key properties:
Bore 125 mm both hot and cold
Stroke 25 mm both (at second run)
Angle 120 degrees (at second run)
Air, 2...3 bar absolute.

Main things to test are:
a. Using mono-channel as a heater, regenerator and exchanger
b. Rolling diaphragm (like in NASA engine) as piston sealing
c. My own linkage with counterbalance for each piston.

The second test showed that all three at least alive an could be used in further projects. The test was without power load because I still have some problems.
