There's no way a standard combustion will blast through 3 layer foil. And your idea will yield nothing but threads that chew though your burst disk losing it's air tightness.

Yeah you should just drop the multiple disk idea. If you want a louder bang you need a burst disk that bursts at a higher psi (assuming your cannon can perform at a higher psi) and no barrel. Remember louder does not mean you have a more powerful gun, it means you have a highly inefficient gun that ...

It doesn't work that way your burst disk only works if it's between the chamber and the barrel. In your example the projectile is on the wrong side of the disk. Also burst disks take quite a bit of energy to burst. If you put multiple disk seperated by different lengths you would get diminishing ret...

I don't think you understand how a burst disk works. If you tried what your saying here you would find that your projectile woulld get stuck somewhere in the barrel.

Ok now you've crossed the line from just honest questions into the realm of handholding type coddling. I gave you the benifit of the doubt with your first post, but now I'm going to agree with mavrick.

It's hardly the best. In my experience it was only barely average. Butane and carb cleaner are great for spray and pray designs. Or if you want a spudgun that is really good use propane.

Good that you started something finally. I hope you like the burnt stench of ol' spice because once you use it that smell never leaves your cannon.

Nope, it works best with a larger gun. It tends to flood smaller ones due to it's potency. It will leave a lot of soot in your chamber though.

I use the one TRUE fuel, steeped in tradition passed down by our spudgunning fore fathers, fermented boar feces. Note I said boar specifically. Pig poop is just too weak to really launch a potato. Also steer clear of hog and other types of swine as most often they prove to be too powerful and can re...

Wow, if Ironman and a plumber were to have some unholy child, I'm pretty sure your gun is what would result. Very fun to look at your stuff!

Hell my gun can do that (when vent is opened) and it will put a dart through 3 two by fours.
