where/what is the ignitor? Get some more pics.

The ignitor is on the bass of the cannon, attached to the screw lid.

Look Carfuly before posting Usless comments.

Btw, its a Piezlo Sparker i beleive. (Push it and it makes a spark )

Might have got the name wrong but eh.

[xpiC]

I think it is a Piezlo Sparker,
It works great. and it was easy to wire up duel spark.
I just havnt put it in,

[spudkilla]

That's a really bad idea to mount the sparker on the endcap. If you fuel the cannon and load it, whats gonna happen if you drop it? Yeah...Kaboom!

[xpiC]

spudkilla,

Yeah i know, i only mounted it there as a last resort.
I have another cap and im planning on mounting the sparker on my handel i just havnt put it on yet its still drying.

[pat123]

looks nice, but those threads look really short and that looks like a reducer instead of a bushing.

[SpudFarm]

it is the same as i used on my first gun, my cap blew.
hurry up on removing the ignitor.

[xpiC]

Yeah its nothing to big,
i plan on building something a little more bigger later on
but this was just a quickie

It's called piezo (pee - zo). The PVC/ABS pipe and connector parts look thin and weird. Are you sure they are up to the task of keeping you safe and out of the emergency room? Where are you located xpiC?

Because of its short length, this little puppy will be loud.

This cannons not ment to be the best haha its my first one ive seen worse

[vovka351]

Nice... i have yet to build a combustion of larger bore than .75 inch

by the way, can you get your hands on a disposable camera? you can make much better ignitors out of those.

[bigbob12345]

that doesnt look pressure rated at all
If I were you I would just scrap it and make another one out of pressure rated parts(if they are avaiable to you)

But I guess its a decent cannon...for your first

I'll defer judgement on the PVC stuff to someone in the Oz/NZ locale...it does look suspicious though.

Your cannon doesn't have to be the best...you just don't want it hurting you.

[xpiC]

It's presure rated PVC?
I'm pretty sure
Yeah im thinking of making my new one out of ABS?
But im not sure.

Any idea's?
