not bad, i dont see why you couldnt do that with brakeline and a drilled out compression fitting, that way you could make the 90 degree turn easy

or you can always shoot a higher pressure gun from inside but behind
or you can put nails in a spud and fire it like a mortar

this wouldnt work IF the disk can flex

This is more complicated than I need. Basically you're saying "shoot" the disk? I may make a mortar version but how do you get the potato to slide down?

just make a potato slug that fits perfect in the barrel, put a nail all the way throgh it length wise and grease it up really well so it will slide down the barrel easilly all by itself with no ramrod. it should be plenty of time to get your hand outta the way.

use nicrome wire , i use it to trigge all my burst diskes it burns through them so fast, or get another chamber and exhaust that into the chamber with the ball valve, or put a ball valve just behind the burst disk. :D

I thought about heated wire but I had no idea what kind or how to heat it.

Correct me if I'm wrong, but I think nicrome wire is the same thing they use in toasters for the heating element. If you could set up a miniature "hot plate" for the burst disk to sit on top of (in the union) and wired up the nicrome to an appropriate power supply... yeah, I think it'd work great. However, it seems like a lot more trouble than it'd take to mod a sprinkler valve.

Peace,
Pete Zaria.

Have any of you seen a resistive element go from cold to glowing in 0.001 seconds? You'll never see one, unless it's on a one-way train to vapor state. What I'm saying is that the wire won't become hot enough to be used in such a way. It'll only burn a small hole at first, which is no better than using a nail to puncture the disk.
Why doesn't anybody use the electromagnet idea I posted a few weeks ago? I'll post a diagram soon to clear things up.
