Its run off a single air ram which i purchased off ebay... didnt really need one this big but it was dirt cheap so i grabbed it anyway. Its got a 50mm bore with 150mm stroke. Its just plumed into my arb high output compressor. 100psi is heaps to run this ram.
My mate got me the solinoid and the control valve. I think you can purchase them from places like a mans toyshop.
The bar itself is a peice of 25mm solid stainless and the light tabs are stainless too. Then i got bearings and bearing holders (not sure of the technical name sorry) to suit the stainless.
It was pretty easy to do, just a bit of stuffing around gettint the mounts in the right spot so the ram worked properly.
Anyway heres a few piccys to keep everyone happy. Threw one of my ute that i have just about finished making a tube tray for.
