Hi! I am interested in building a simple single shot gun. I was wondering if this would work (doesn't have to be very high power, just, ya know, shoot bbs pretty fast) ? Id like the bike pump to give a 1 pump: 1 shot ratio. Is this feasible/what pump should i use? What type of valve is best? I really quite new to this, so thanks for the help/links to references and examples

Looks like a solid design and if all tolorances are tight, using a small chamber you can get a shot per pump. Study "hammer valves" , "spring loaded ball valves" would be good choices for your wants.

I like the valve design. I've seen it done before with pretty good results as well. How are you planning on triggering it? It should be fairly simple although I'm curious.
Whatever the mind can conceive and believe, it can achieve
