So many people do this, they ask how to build an advanced piece of technology without doing any research. Look around the site for about a week and you'll find at least 6 semi-auto designs. Try building a standard pneumatic first, that's what I'm gonna do even though I know how Semi-Auto's work.

how all i have is a airtank (kinda it needs to be pumped and doesnt last as long) and some tubes

Can you use grammer and punctuation please? Its hard to read a long list of letters and numbers. I mean within reason.

Questions:
1. Pneumatic, Combustion, Air Supply?
2. Are you going to use an air tank or no air tank?

And a chamber (I like the simplicity in this one):

i think the first step would be Puncuation, then you can use grammar.
But make something simple first of all. Try something rly small and cheap, if you dont wanna "waste" time and money. like the "Mini nail gun"
all you need is some metal pipes, blowgun/ballvalve, some adaptors and other crap!
