What on Earth would I use?
Badman
Aluminum (from a pop can), plastic (from something like a gatorade bottle), aluminum foil.
cant think of anymore atm.
Go with what frank said, i think that will be better.

Ahh yes of course, very thin sheet metal..Why thank you.
Badman
Whole rolls of alluminium foil
Indeed, sheet metal would be better.
Though on a larger scale and pressure, burst disks become really expensive.
You may not need any projectile anymore because the BD shrapnel already rips stuff apart. (Larda's 200X hybrid)
What pressure are you using?
The thickness of your burst disk matters not only by diameter, but mostly by pressure!
You could also try other sheets:
Sheet pvc or other plastic, maybe wood if you can get it to seal.
Circles of sheet metal out of the doors and hood of your dads or neighbours car...

It's only in 10bar rated PVC, but has a setup similar to that of sgort's burst disc pneumatic. With a pneumatic actuator. I'd be using it at around 100psi.

I'm not using a 4" PVC Union. I'm using Camlocks.

Not really, it was the cheapest option.ilovetoblowthingsup wrote:4 inch cam locks wtf! Them things are expensive!
£30 ($60) for both the male and female parts. Aluminium ones that is.
@D_Hall: Indeed. Although if I do eventually use Aluminium Foil, I will need like 200 hundred layers to take up to 100psi and not burst.

A 4" diameter port could be called a good time to transfer from foil to sheet metal.
You could try those thick cardboard beer coasters from bars and restaurants. Probably won't make it up to 100 psi though at the 4" size.
