I was looking at designs for hybrid spud guns: a combination of a pneumatic and combustion (i.e. instead of aquanet or some other fuel that gunks up the inside, using a carefully measured amount of propane, THEN compressing to 60psi or so) No valves on these; you have to make and use a burst disk.

The hybrids can easily break the sound barrier. Of course, the hybrids are incredibly dangerous (schedule 40 PVC isn't strong enough) and should always have a remote system for firing them. I haven't a clue how far they shoot. (Hmmmm... I wonder if dimpling a potato much like a golf ball would increase the range?)

Anyway, I ran across this youtube video of a pneumatic spud gun. I thought it was one of the best youtube videos of spud guns in action:

(The captions in the video made it good.)

For what it's worth, a hybrid gun (obviously a bit more complicated) here

And no spud gun set of videos would be complete without a video of some idiot getting shot with a tennis ball. Had it been a potato, he'd probably be dead. here
And a couple of jackasses who shot a friend with a ping pong ball

Bumping an old thread...:p


I'm interested! I haven't built anything yet. I'm looking to build a pneumatic, to launch larger objects like shirts and prizes.

Of course, if I have to build several dangerous prototypes first, so be it...;)
