about the ball valve and piston thing,how can u find a ball valve that has an exact size opening as your pipe? other then that, you are a genius.

This is pure genius as saladtosser said... how do u come up wit this stuff. also that is an absolutley amazing job with the animations. one question though. in the second to last picture, you show the barrel moving forward and back, what kind of mechanism would do this.... final thought... unfortunatley i think that there would just be to many moving parts and other items to debug to make it worth while...

Forces for moving barrel:
-Blow Back Mechanism.
-Pnuematic cylinder.
-Your Hand!

To make a Auto anything it generally takes sevaral mechanisms. This design I see to be quite simple. I must congrat you on kicking a 9 month old topic, your question were good though.

EDIT:***POOF!***
Ya, I dont know what I was thinking. It was a immature joke, and not a insult. Im sorry if you took it as one, because after reading from a neutral stand point it sounds if so I intended it as a insult. Sorry .

thanks man but im new to this site and i was just looking around... and what exactly do you mean by "you should be used to this motion"... is that supposed to be some kind of imature insult

lol WD-40 lol

I just want to make sure I understand the pump action. The shell is pushed back with the barrel, fires, barrel moves forward and drops empty shell, on the way back a new shell moves up into the now empty space and repeats. If that's right its brilliant! Also, I tried to make the cartridge system, but sometimes the chamber side of the cartridge would fall first and it wouldn't fall out correctly. I could have probaly gotten it to work but I was just trying to make a prototype, if anyone gets any of the theories here to work (Except the valve concepts) I would like to see how they turned out.

i had thoses ideas in my head and finally figured it out, iam going to make the ball vavle thing and the magizine loader
