www.advancedspuds.com is nirvana for all you tinkerers with too much pvc pipe and propane sitting around in your garage. Should you be unfamiliar with the term, a spud gun is the weapon of choice for those looking to go to war with their neighbors and their only ammo is a 20# bag of potatoes.
A spudgun or “potato gun” is a device used to launch potatoes or other produce hundreds of yards. Many variations can be made on the simple concept of a basic launcher. This site is an attempt to record my spud gun exploits and provide details of my launchers and any advanced concepts that may be hard to find elsewhere on the net.
My favorite has to be Revolver X. Although I think the Dept of Homeland Security might just pay you a visit should you actually use it.
