Do you have a chamber fan? A fan is probably the most important addition to a combustion gun, more important than metered fuel or multiple spark gaps.

To see if a fan would help, without actually installing one, fuel the gun and let it sit for an hour or two, occsionally inverting the gun. You ...

And for people who can't buy stun guns

Anyone , regardless of country or age, can buy a stungun. Ever heard of BCARMS?

This system sounds like a fine investment for a handheld launcher though, as it's likely already miniaturized to a greater extent than most of us can manage, and obviously ...

It was just an idea that hadn't really been explored yet. I figure it's got to be pretty reliable and efficient, seeing as how it probably sees a lot of use and abuse over the life of the gun.

And for people who can't buy stun guns, and don't want to resort to using piezoelectric grill lighters ...

So I broke out my gun and played paintball for the first time ina few years yesterday, and I saw some guy using a gun by Tippmann called the C3. For those who don't know, it's a pump gun that uses propane and an electronic ignition source to fire a paintball.

So something immediately clicked in my ...

Sweet gun, nice and clean!

Never been a Slipknot fan, though.

The preview pic is massive! Might wanna fix that!

Far and away, one of, if not the coolest combustion cannon on SpudFiles!

I know what I'm modeling my next cannon after!

Good info. Estes rocket ignitors a little more reliable and safe....

Probably borders on passing the no-discussion rule re. powder/explosives....but no spud gun usage was mentioned in association.

Yeah, Estes ignitors would be awesome. Didn't even think about those. Good idea.

I was hesitating ...

Wanna blow the house up, and have a nice fireball to boot?

Take a film canister, and fill it about a quarter of the way full with flash powder. Then, take a plastic sandwich bag, and cut the corner off of it, fill the cut off corner with a bit of gasoline, and stretch it over the mouth of the ...

Depends on which type of glass you use, I suppose.

The average pressure exerted on the wall of a wine bottle is about 80psi (for VERY prolonged periods) , so I don't see why you couldn't use it for a combustion.

You probably could pull it off, but I wouldn't try it to begin with. Just goin' with ...

Thank you to all who helped =]

Anyways, currently I am waiting for my mom to come with a new can of axe.

So once it arrives, I will record my first potato gun shot into one of the new houses in my new area.

Btw, about the cap situation, as i mentioned before, it was too tight to close...
Am i ...

You really don't have to worry about whether or not epoxy will hold. I'm sure it will hold up just fine.

Given a choice between the two, I'd go with the PVC, simply because it's pressure rated (and for tradition's sake), but I don't see anything wrong with polycarbonate.

It's got a high tensile strength, and it's very resistant to just about everything, including heavy impacts, extreme temperatures ...

Just put in a general search in Google.

I think when I searched, it was something along the lines of "3/4" slip 1/2" slip PVC", and went to the first page of ...
