The burst disk idea is good its just the problem of the gun firing when you dont really know. I might consider it, but right now I just want to make things as simple and cheap as possible and get it built, so im using a ball valve for now. But I might choose to do a few upgrades further on in time :...

Dry Ice propelled gun
Hi all my friend am I are about to proceed in building a pneumatic cannon that will use dry ice to have a constant source of pressure. We will be using a galvanized steel tank and will hopefully be able to run it at about 10 bars. The firing mechanism will be a ball valve, what are your thoughts on ...

Cannon Hall of fame
Hi spudders Don't you think that a cannon hall of fame of some sort on this website would be great? I think it would be nice if the select few of truly outstanding, honourable and innovative cannons can go into it and be viewed by all the users. And of course if you win the competition on spud files...

C:B Ratio Decision
Hi fellow spudders I'm new to SpudFiles here, and I have a question. (I did search) My friend and I are planning to build a combustion cannon, and I am yet to work out the PVC dimensions according to an ideal C:B ratio. I have looked on the spud files wiki, and I read that "a C:B ratio of about 0.6-...
