Here it is My combustion for destruction.

VID:

Definitely the highest pressure rated basic combustion I've ever seen

For that weight I'd like to see it become a hybrid so you're getting the most out of having to lug all that metal about.

As it is though I think its pretty snazzy and well made

This is a neet looking cannon. How are you mounting the fan? Is it just slid in there? What kind of fuel are you useing? Last question from me -- Are you going to post video's? If you do, please use Photobucket or Google, Youtube works well to, Plt~~~~~ on Putfile.

This cannon could be converted to a Hybird.

I agree with the others, it should become a hybrid. If you don't want to do that, you should definitely add propane injection.

Very nice piece of work.

I agree with the others that stainless steel is overkill for a standard combustion -- you're talking ~30psi to contain. That beast is screaming to become a hybrid. I say, "Cry havoc and let slip the dogs of war!" which is just a fancy way of saying, "Don't forget to post the damage pics!"

Thnx m8 not to sure if will become hybrid yet although it weighs a bit its not to bad if i was to make it hybrid i would need a stun gun circuit unfortunetly illegal here will soon be getting oxy /acetylene cylinders mounted and metered should b fun then

just thought ill put the pressure ratings in for the chamber:

Stainless Steel Properties as follows:

S/S 101.6mm (4") Outer Diameter x 2mm Wall thickness

Working Pressure 646psi

Bursting Pressure 3038psi

ok yer so far fan is just sitting thr but will b making clips wen i get time, secondly atm im using pure butane lighter gas, third yer there will b vids (youtube, or g video) um yer and i sound real dumb askin this but actualy what defines a hybrid form other cannons?
there will b damage vids and pics
cheers

A hybrid uses compressed air and fuel.

wouldn't it be a lot easier to use oxy/acetylene in this thing??
It should be okay, if it's rated that high..

You can order stun gun circuits from sgort87 at his website:

When the stun gun circuit isnt in it orginal box its legal,So he could just ship you the circuit and your good to go.

ok thanks guys for all this have learned much already will keep improving my launcher atm im working on the fan then if my dad lets me use his credit card might think bout that ignition.

C@SE-G

That is a nice gun!

I like how the ignition is achieved as well. It looks as if the - wire is going through a wire straight into the chamber, and the ground is hooked up to the gun?

Also, what do they use that pipe for where you live?

yer um ok im 16 and i work with my dad as a part time job as a boilermaker our company does jobs on site at a pet food plant called M.F.A.N.Z (Master Foods Australia and New Zealand) all the machines,condute,water/drainpipes,pumps,tanks..ect.. have to be food grade (no rust) they have high volume pumps which need pressure rated pipes on them so a short trip to the company scrap yard found me a 4" chamber and end plug also 2 1/2" barrel i know how to tig weld properly so that you do not end up with excess steel on the inside of the weld.

cheers

C@SE-G

Nice gun bro i cannot suggest anything other than grenade launcher

haha

Tobe

does anybody no how to measure aerosol cans buy (make) valves for this.
