Provided By - DR
Here is my Burst-Disc Launcher. This Chamber will be modified to run on a 2x mix of propane and 15psi of compressed air (which is held back by a burst-disc). You can fire this is a simple pneumatic, as a regular combustion, or as a Hybrid when completed. Future plans on modification to the Chamber will include spark plugs tapped into it.
There is a male 1/4NPT quick-disconnect in the end cap, a Chamber, a Union, a Burst-disc, and the barrel.-- No valve, no restriction, just 130-150psi out of any barrel.

Do you have a pressure guage on that thing? if not then how high do you know the pressure goes before the disk is "burstified"??

I like how it has so many capabilaties, like a 4 in one, just mount a bbmg on top, then a 5 in one. What do you use for a burst disk? Soda plastic?

Choice rephrasing would translate to:
DR, what kind of dirt bike is that?
Maybe that clears things up.

What you a re doing here is similar to what I've been doing with my latest cannon. I use a 3 1/2 oz drinking cup stuffed at the barrel end of the combustion chamber , add extra fuel ,add air through a tire valve in the end cap . and then kaboom , sends a 2" spud up to a 1000 ft. I hav e about a 17" chamber with a 60" by 2" barrel. I also have a 60" by 1 1/2 " barrel. by using the cup ,extra fuel and air , they shoot about the same distance . I have a stun gun that just c ame in today but I am hessitant to install it because it will be harder to put the cup in place and I seem to get comlete combustion anyway as it creates a very thick smoke in the chamber after firing. I may have to use the stun gun in one of my smaller c annons.
