One last mussing... Would it not be an idea to use a colapsable membrane (Big Plastic Bag) for the gas inside the delivery cylinder... I would have thought that the relativly large surface area of gas in direct contact with water could lead to moisture problems...?
I had a reply on a previous thread(sorry cant remember who it was) suggesting using a weather balloon as a gasbag,I suggested putting it inside a roto(roughly the right size) to protect from wind/sharp objects etc
; any good?
