Not really a laser, but still interesting for who love mechanics.
So today is THE day to restore my Stirling engine!
This is a twin cylinders assembled in 2008, which didn't started for 2 years. This amazing engine works as an external combustion cycle, "alpha type" working mode.
I disassembled it, cleaned all moving parts like ball bearings, rods and the axes. Some ball bearings have been replaced.
How does it work :
