@Willdebeers 60 psi? That sounds kinda low are you sure thats it?

Is there any chance of my pvc pipe failing or busting apart on my spray and pray? I have been told by other cannon users, that I should trash my half assembled combustion cannon and use some abs pipe instead.

wait longer after ignition?
more ignition or fuel?
what fuels have you tried?

thanks for the cool links
I am currently building a basic combustion cannon and im using a bbq lighter for ignition because I have easy acess to them.
after what you have told me, I may use propane instead of the classical hairspray. If I build it with an extra long barrel will I have increased ...

holly cow! great damage pics

thats a really nice canon pic! :shock:
but why did you decide to make this cannon all metal?
you should considder making your combustion chammber larger.
I really admire that you are keeping it original and making a combustion cannon rather than rigging it up to propane or air!
Nice job, 8) keep it ...

shoulder mounters are dangerous!
nice gun, I admire that you have a giant chambre and a tiny barrel.
Does the mini barrel make loading easier than a large barrel?
you should build a handle of some sort to take away the danger of blowing something up next to your face.

wow, that is a beautiful canon.
i really admire the shotgun look.
does your combustion chamber ever get warm after use?
