Here's a firing action I designed two days ago. It's heavily inspired by the way modern automatic rifles work. The neat thing about this design is that it cycles AFTER the bb has been fired, and always fires even pressures are too low to cycle it (you cycle it manually, in that case) .
(Animation takes a while to load)
(Note: I have not drawn all the rubber bands and springs it would be using.)
It works with two hammer valves. In a conventional rifle the gas from the cartridge drives both the piston and the projectile. In a gas gun pressures would have to be too high to still be safe, so I came up with using two valves instead. Once the hammer strikes the first valve it releases a second hammer, which strikes the second valve. The first valve drives the bb, the second the bolt.
But, the best part of it all...
...I found an easy way to make a fire-mode selector switch for it!
The fire-selector is something that I still need to improve a bit, though.
Anyway, I'm quite excited about it, and I think I'm going to give it a go some day.
Any thoughts? Better solutions? Criticism?
Please do reply!
