how does it works, i do like to build a fuel inject system,but don't know how

Some one plz help me,I'm really new at combustion cannons. And i'm trying to make a mini one first,i used a chamber fan,a spark ignitor, using a mix of butane and propane.But a can't get it ignited!! :x some body plz tell me why and what's the basic things i need to make a good mini combustion canno...

thx,i will start now

What well i'm going to shot bbs, so and you give me a guess of the power i would get?and some close pics of the size and postion of the fan plz,send to my e-mail:wyz2285@Gmail.com

thanks for help:D,but the chamber is metal ou pvc?

it's hard to fined a pump that's pump up more than 10bar

I'd like to make one like this,but where did you got a fan that small?and can you get a list of materials i need

Once again, great gun, can't wait to see some damage pics! You have left out lots of details though, Does the blow gun just let out a small burst of air or is the gun hooked up to an air supply? and when you said, well i use a magazine that works like a shot gun,but automatic. You are very unclear ...

thats epic, i want to make one now! nice job! 15 psi or 15 bar? right,i meens 150 psi :lol: Looks very nice, very clean construction, i like it. And you should deffinately crank up the pressure, 15 psi is nothing. you could take that up to 250 plus psi no problem. You would notice an enormous power...

This is my latest build,a semi auto sniper rifle.With 150 psi i can chose shooting time from 3 to 15 . The barrel is 6mm in dia and 40cm long,1/2QEV pilot by a semi auto blowgun,30cm 1' chamber.This gun is accurant too it's great to shoot a apple at 30m .Damage pics
