here the concept

Looking nice but I don't get it (I'm stupid I know)
I like that it is complex. Mayby hard to do

think about it! it isn't so hard.

I think it over night and understanted part of it.
But how you thought to make air thigh magasize or burst disk for full auto?

Why not have a premixed bottle of fuel and air and feed from that instead of going through all these complications to mix it in situ.

@finland66 there is no burst disk or airtight magazine necessary maybe a blow forward bolt or something like this is adequate.
@jsr i know what you mean but it isn`t practical for higher chamber volumes and the most important is my proclivity to make complicated things easier or to figure out what is nessecary to make this thing buildable without changing the whole concept.
you are one of the persons from wich i need help to improve the concept into a easier to build version
...and a pistol without bulky tanks an so on... isn`t is a nice imagination^^

@jean still you need air thigh blow forward bolt, but it isnt a problem.

no need for airtight
it is hard for me to explain
while the combustion happens the green piston moves back ....pressure extends to the barrel and drop down...the yellow piston start to move from left to right, vent the chamber and sucks new air/fuel behind it... (this is the moment the drawing show us)....than the green piston loss his velocity and moves back against the yellow piston, push it back to left and the fuel/air mix can reach the other site of the yellow piston. the piston strikes the fuel meter...ignition..
i hope you can understand it

Aaaa i get it 
. You explained it well, but how the mixture on left side the yellow piston get on the right side of yellow piston to ignit mayby check valve on piston.

the red cup shape works like a pump head / check valve

mh not even one comment to improve the design

Well, have you tried it yet? I can't really give much input without some results on your current design.
Posted: Tue Jun 25, 2013 9:12 am
well this is the fundamental concept but there are some problems to solve before start to build it. this design is relative complex and need some skills and tools to build. the goal is to make it buildable with tools in the basement. (no lathe or extraordinary machine skills)
-will it work?
- is there any way to reduce the numbers of o-rings?
- any way to make the fuel meter more simple
- may an other configuration of the components
- make it serviceable..
what ever... i need suggestions
at the moment i cant build this thing because there are to many problems in fabricating the components... example: is it possible to make the fuel meter absolutely air/gas tight? or is there an other way to meter without the need of absolutely air tight.
if the topic is a little bit more complex you get only a few comments.... what?
i am restricted in my language skills to argument in a detailed way sorry

Have you looked at the Tippman C3?
Posted: Wed Jun 26, 2013 8:55 am
hi jack
yes i saw the c3
but it isnt a full auto and you have to cock every shot...
there are serval design that work like the c3.
may it can work as auto but i see no way to not cock the cannon after every shot. not yet..
my previous post seems a little bitter.. sorry
there are serval points to figure out but i cant do it alone
