looks alright but i would have put a tee in instead of the 90degree elbow and fixed the stock into that, the stock would then give you more chamber volume aswell oh and i would also have mounted the blowgun inside the two elbows.... and make sure you get those damage pics up
thats definetly a nice gun. that hose connecting the blow gun to the sprinkler valve is it pressure rated ? im only asking that as it looks a quite thick and doesn't appear to have those strand of metal or plastic in it to strengthen it. the last thing you want is your gun piloting when you don't want to.
its really hard to tell the C:B ratio just by looking at it but the way i tell my C:B ratio is just pour water into the chamber until it is full and measure it then do the same to the barrel. then just simplify or divide or such till it is in simple forms. Example:Chamber=10.9 cups, Barell=9.8 Cups or 10.9:9.8 then just simplify to get your ratio. Hope this helps.
Great cannon too i like the handle.

I haven't really tested it, but the ones I've built...well, I think this statement is just a little over-rated.
As far as the C:B, it is definitely less than a 1:1 but it is hard to tell as of now. What is the size / length of the chamber and the size / length of the barrel?
