Last week I made two hydraulic cylinders. The cylinders should be able to hold the crane boom in position. Therefor I additional made a “clamping” ring from ash. First I tried to do this with a rubber ring but finally I prefered wood.
(I,m making two cranes at the same time, that’s why sometimes you she two cylinders)
Below you can see how it was done.
Thanks for watching.
