I have been thinking about the discussions on triggering burst discs for a while and thought it would be nice to have an easier way to do it than using two unions and all that.
I decided to also cure the problem of bust discs being a royal pain in the ass to replace.
This is it what I came up with: The Quick-Change Triggered Burst Disc Cannon. I'd like to let my video do all the talking. (Be sure to open in Full-Screen.)

Enjoy.
And for some details:
What it is, is a lathed union inside of 2.5" pipe with o-rings on it (like a piston) that locks against the other union piece held in place on the front. Air pressure keeps it held in place naturally. All I have to do is bring the "piston" up to the aluminum and it sticks right on.
I tapped into the broadhead and threaded it onto a threaded rod which then threads into the pneumatic cylinder.
This is a prototype model which is why the barrel is not cemented in, stickers are not removed, and it's using "Kevin's" chamber. I think it's still pretty cool...
?
Talk about an imagination overbudget.
