Ya I notice it now.

You get build the vortex block out of JB Weld. It comes in large industrial tubes and small tubes. I think it is stronger than bondo but its kinda expensive.

I know the top one is a vortex but I don't get how this one works. It doesnt look like a vortex. http://www.pipersprecisionproducts.com/ ... -Flame.JPG

I got to thinknig about it and I think its a cloud. I think the bigger pipe where the front handgrip attaches to is a large bb cloud chamber and the T fitting in the back is where the air flow agitates the bbs and sends them into the barrel. Whatcha think about this idea?

I found this airsoft flamethrower but I have no clue how the bbs get from the packpack tank to the barrel and if it is using a cloud or a vortex. It is the second flamethrower towards the bottom of this page. http://www.pipersprecisionproducts.com/flame_thrower.htm Any ideas how the ammo feeds to th...

From my experiencing melting them together maked more power and more smoke.

Try a 3/4 inch QEV from http://www.valvestore.com.

Air or co2? Also it is easier and safer to buy one because a regulator must work perfectly or you will get to much pressure and your tank might rupture. I also sugest putting on a air safty valve incase of overpressure.

Ya, I have my 1st cannon (completly out of ABS) Blow up in my hands. It didnt shatter into hundreds of pieces but ripped into 2 big chunks but the sound (it was shoulder held cannon) left me deaf for 2 days out of my right ear.

Even more satifying is a big red button with a red warnnig flipup cover over it and a red LED.

ya i think i need 1/4 inch

Iono, diff diamiters but the tube I found on mcmaster is .120 wall thickness and I don't think thats thick enough for threads. Right?

I don't know. I was looking at this kit to get for making the threads. http://www.northerntool.com/webapp/wcs/ ... _200243574

... so screw it together very easy with some plumbers tape? and about what wall thickness do you recomend?

I dont have the equipment or experience to weld it so can't I just thread it with a hand pipe threading set and some clamps?
