Lever Action Shot gun

[sumisukyo]

Hey guys long time no see,
after writing my exams I went on a very long holiday with my girlfriend to Durban
got my Matrix results... I passed
Got accepted to Open Window
and now I have to think of a new way to occupy my time, and while playing my new favorite game Fallout : New Vegas, I stumbled upon my next build a lever action shotgun
So with this i have a ruff idea of my build
sort of a pump action instead of using the pump action to reload you would use it to pump the system for re-fire effectively making a sort of semi auto system if i can incorporate a small bb-gun ammo clip

so e.g

connected to a small chamber
PLUS



and a Barrel with a low pressure spray gun

would equal


So any helpful tips to put me in the correct direction with parts needed and pressures to make this maybe a bb-gun or maybe if you can get enough pressure in one or 2 pumps a pellet gun.

Rules;
To make it authentic and probably because it will have a reload function as well it has to be a powerful pump that fills the chamber in a single action.\

Its Good To BE BACK !!! [/list]

a powerful pump that fills the chamber in a single action.

I'd suggest a design like a PCP pump, a sort of coaxial multi-stage. To ready it in even two pumps is a little optimistic, but probably possible.

I'd suggest a coaxial piston valve, that will probably fit best in the shape you're trying to achieve.

this is NOT going to be an easy build by any measures. Its going to take a lot of custom parts and compact fittings to get anywhere close to that form, but I hope for the best, and I would like to see you pull it off...but just know what you're getting into

It's time for me to try and get some sleep, but this might provide ideas/answers:
