It's been far too long since I've posted an Instructable. But rather than list a bunch of excuses, let's get started on today's project.
My latest airgun build follows a design called a cascade failure double burst disk system. This is the most powerful and efficient gun I've built yet, and is relatively cheap: the whole thing cost less than 40 USD for me.
If you want to make something more efficient, powerful, and unique than the generic ball-valve, diaphram, or piston gun, try looking into burst disk pneumatics and designs such as this one.
PLEASE do not try this if it is your first cannon/airgun build. I will not be held responsible for injuries involved around building, testing, or shooting this design. Failure to do research can lead to exploding pieces and severe injury. This Instructable has been written by an experienced builder for others seeking new designs and challenges, not novices.
Special thanks to Spudfiles for having so much knowledge available. I built this gun after reading on that site for about four days!
Thanks also to jackssmirkingrevenge on Spudfiles for answering my questions about designs and linking me to more info.
Side note: I'm not sure what category this should go into. Anyone have some suggestions?
