The ayes to the right 4, the no's to the left 0, the ayes have it, the ayes have it!
Thanks for your suggestions all, its very much appreciated. I would also like to say my intention is to now CAD design the crane and have it 3D printed. It will be based around the recently acquired chassis and should be very cost effective as well as giving me a break from card modelling! Hopefully I will post some basic images of it tonight, I'll see how it goes!
