« Part 5: Kerf making Part 6 of Hydraulic Crane (Toys and Joys) series Part 7: Hydraulic cylinder »

According the plan the boom of the crane is equipped with spacers. But when the humidity change also the fitting will change. Therefore I made (wooden) springs. The boom is made out of ash. And ash is great for making a compression spring.

Thanks for watching.

Good thinking. Those springs will take up any slack in the sleeves nicely.
Someone could also make a camera tripod using these as adjustable legs.

Your spring idea is a very clever and simply solution.
