Lol, Most of my friends know this, I really dont think before I say/post things. I honestly didnt mean that it was ghetto. Well, in my head, ghetto means homemade. I wasnt trying to make fun of it or anythihng 8)

@pvcpsyco, You didn't have to explain all that.
For future reference, I found Ragnarok's list for you:

Ragnarok wrote:My definition of ghetto is that it must have at least 3 of these:

1) Made without measuring anything
2) At least two kinds of tape, PTFE does not count.
3) Minimum amount of money spent
4) Less than 50% rated components
5) Made while bored
6) A tool was used for a purpose other than what it was intended for in the construction
7) At least partly biodegradable.

So, it's both the materials, and the way it's made.


Anyway, a one way valve like the self made one would be useful (probably necessary) for a design like this:

At the front end where the mag. and barrel side, but not shown in that animation.
Very useful valve in the photo jimmy101 provided.
But for semi you still need a way to load semi which is do-able as well. 8)[/url]

What if you were to install 2 chamber fans? The fans would blow in opposing directions. use a big fan to vent and a smaller on to mix.. and you could drill a sirese of hole in the end cap and cover the inside with a thin layer of rubber to build a check valve.

this may just inspire me to build a combustion gun :shock:
