Nice idea bdfd, but where are the solenoid valves, pipework, limit swith's and compressor to make this work?
And what about the cylinder length 40 cm of movement means atleast 60 cm of fixed cylinder

Only higher cylinders are seen. [:D]
All pneumatic parts are lower in the walls, sheltered from 'cold' winter and wet spring or autumn. [;)]
