how do you make 1.5 in. burst disks

[windshrike]

Do you want to know what material or the entire thing including the holder?
Materials: aluminum foil, plastic wrap(several layers), or anything you can think of

The holder: It's a 1.5" threaded union. You hold the material over the female end and screw the male end into it(or vice-versa)

If you don't get that, try the wiki. If you are still confused, wait for someone else to repl.

ya but when you use burst disks make sure when your filling your chamber your behind the gun becuase, SOMETIMES homemade burst disks can be unpredictable.

The burst disk material also depends pn the pressure you want to raise it to. It can vary from stickytape to plastic boards.
I suggest *aluminium foil for this size, and if you want higher pressures, double over the foil

*Yay for the proper spelling of "aluminum" foil
