Here's my gun. It fires bb's, spitballs, and food =). Very ghetto =p. I'ma get my fish food can as it is a big container that's fits in my hand so I will scrap this container and use the fish food one =). My gun shoots around 50fps at peak which is very rare. How can I up the fps and measure fuel? As you can see I am a Taekwondo competitor by my sparring gear =p

Try looking up "fuel meters" something from Jackssmirkingrevenge.

You've got a start and now your hooked, don't fight it, just research and build, improvement will come naturally.

Exactly what he said. My first "cannon" was JUST like that. But I was hooked, and I even knew more about them BEFORE I built that little one.. I just built it for fun, and then a few months later, I made a pneumatic rifle, all from watching youtube videos. You'll get better!!

Scrap the one you have (bin it)
Get a decent sized chamber (60ml+)
Get a syringe
can of butane
long barrel
and some plastic bags for burst disks.

..... :roll:

For airsoft, I found that less than 50 ml's yielded bad power. An airsoft combustion usually calls for a detent since the pressures generated when shooting a 1/4 gram airsoft pellet is laughable.
