Chamber: 2.5 cm long, 9mm i.d (it is longer, chamber plugs occupy a large amount of space)
Over/under construction with chamber brace and fore barrel support.
Chamber plug is threaded and has a built in check valve
2 spark gaps
Propane, MAPP or oxygen-hydrogen fuel (metered)

Inspiration, the Cobra Venom by Moonbogg:

Will I do an instructable? Depends. If someone suggests a good cannon for me to replicate (on SF) I might.. make one. Though these are very intricate, requiring a lot of understanding, planning and determination..

Also, my camera crapped itself so photos are taken with phone.
