ya, that was the gun that the guy who had me make this thing showed me right at the beginning. i remember when it was orriganally posted on the awful forums in that video i was only using 50psi of pressure in the chamber, i wonder how far the flame would go with 90psi and a slower burning fuel. ill ...

well im all done with it. took a vid after cleaning pvc shavings out of the gun that went unseen during assembly.

thats the exact link he sent me when he first asked if i could do it. ive thought of the propane tank to pressurize the main tank. i have drawings for a flamethower that i drew up years ago that was just like the gun i just made but with propane as the air pressure. never got around to making it. it...

ya spudshot is right. keeps the flame from traveling up the line. just tested it for the first time. OMG!!! is probably the best way to describe it. i first set my lawn on fire but it went out quickly. i then decided to go into the street. lit the street on fire but that went out after about 30 seco...

a blow gun would never flow enough fuel. not sure on the volume but for those math types out there, the virtical pipes are 24" long and the whole thing is 22" wide the layout is exactly the way the customer wanted it with the exeption of the tank. he wanted it to only have 2 virtical pipes and be ma...

i dont really do much building anymore unless i get an order for something. i was asked to build a flame thrower by a guy that lives a few hours south of me. other then a schrader valve and pressure gauge its ready to test. ill get pics of that in the next couple days

its all basic plumbing stuff. the regulator is made for compressed air and so is the hose and some of the metal fittings

if you put a restriction in it, it wont focus the power, it will just choke air flow. once the air makes its way past the restriction, it will not focus right down the center, it will expand out to the sides, then go up the barrel

oops, didnt even see that diagram. old age sux

glad you liked it. have fun with your metal hybrid, cant wait to see pics of it

just use a one way check valve and a normal air pressure gauge. you hook the one way valve to the chamber. to that you hook a T fitting. one end has a blow gun to reliese the perssure you just made, and on the other end of the T fitting you put your gauge. this way when you fire the gun, the one way...

ya, spudshot is right, the 5/8" brake line will be your best bet. it will also be the cheapest tube you will find

you had to be looking in the wrong section. did you ask for help?

it will work. just put an all-thread bolt through the pipe so that the projectile always sits in the same place when loaded. this will also give you a .8:1 c:b ratio

your asking for an explosion with that
