[NightHawkInLight] a.k.a. [Ben] just recently developed an remarkable high power air cannon out of PVC pipe. PVC air cannons are great, as well as everybody ought to develop one of these at some point in their life, however what truly makes this develop outstanding is the valve. [Ben] produced a piston valve for this cannon that can be developed with parts sourced from your regional house supply store. anybody can develop this thing, as well as everybody should.
Instead of utilizing a sphere valve or other such contrivance to dump air directly from a reservoir into the chamber of this PVC air cannon, [Ben] is utilizing a much much more smart design. This is a barrel sealing PVC air cannon, with a moving piston sealed against a rubber hose clamp in the barrel. adding air with the fill valve moves the piston forward, enabling air to leak into the reservoir. The air supply is then disconnected, as well as the set off released triggering the piston to relocation backward. This releases all the air in the reservoir into the barrel instantaneously, resulting in quicker ping pong spheres as well as potatoes.
The original set off for this high power PVC air cannon utilized a easy sphere valve for the trigger. [Ben] didn’t such as this service – it was difficult to open as well as somewhat unergonomic. The sphere valve set off has because been replaced with a valve from a sprinkler system, providing this high power PVC air cannon a elegant brass trigger. It looks awesome, as well as can kill a watermelon from twenty yards. What much more might you want in a high power PVC air cannon?
