Plumbed And Ready: Building The Hydraulic System For The Screw Tank Project


Plumbed And Ready: Building The Hydraulic System For The Screw Tank Project

In my prior line of work regarding helicopters, I was an electrician, a technician, an armament tech, a vehicle maintainer, and just in case all of that wasn’t enough, I was responsible for the aviation ground power supply systems as well. That meant that I was overseeing the general maintenance of the AGPU (Aviation Ground Power Unit) systems, which are a turbine engine on a self-driving trailer that supply electrical, hydraulic and in rare cases, pneumatic power to aircraft. I’m pretty sure I never used the pneumatic systems, and the electrical system was easy enough, but hydraulics scared the hell out of me. For the Kiowa Warriors I worked on, hydraulics required over a thousand PSI. Care to guess what that will do to you when a hose lets go? I’ve seen the photographs. It’s not good.

Happily, the hydraulic system that Colin Furze has whipped together for his screw tank project isn’t going to be pushing anywhere near that kind of pressure.  In fact, maybe fifteen PSI will be enough to get the screw drives turning…at least, that’s what the happy little gauge covering the operation is suggesting. It’s the thing about Furze…he comes off as a case against too much caffiene in the morning, but with his love of engineering and his history of work as a plumber, there’s some fantastic fabrication going on.
