Close up of the Y guying. I liked that I could incorporate pneumatic functions. The arms are fragile but function when strings are in tension.
Pneumatic switches are located at the end of the boom to minimize the amount of tubing required. A single tube runs down the top of the boom and the idea is to route it through the turntable and have a hidden compressor and air-tank at the back of the crane chassis (there is room there to work with)
