Part 2 : http://www.youtube.com/watch?v=kMaK33CnINY

A fairly detailed look at a Barrel Sealing Piston Valve for use in a Pneumatic Cannon (air powered potato cannon). Barrel Sealers are the Cadillac of spudgun valves; easy to make and very powerful. This video is intended primarily for spudgun builders and will probably bore the pants off of regular people.

  • Any way you could post an itemized parts list?

  • @TheMaskedAbbot

    Never took the time. Plus, most of the trick is modifying the parts you buy.

  • Hehe he sounds like mr Garrison from south park :)

  • @DannyCrizzleMyNizzle

    Drugs are bad. M'kay.

  • How many psi?

  • @kbckiwi With that heavy piston I haven't gone much over 100 PSI. If I can engineer a lighter one I'm sure 150 is possible...

  • I am making a 2 inch valve. Should the pipe that the piston seals against be 1.5 inches or 1 inch. Does it make a difference.

  • Dude if you had big tiddies, a puss, & was hot I'd say I love you! Thanks for this awesomely done vid. My son & I built this over the weekend & I don't know how but the little shit actually took a bird out mid freakin' flight. Blew my mind. Thanks for the info. You're our hero :)

  • pay you 125$ to build me one

  • Do you reckon you could make it a double barrel if you added a barrel on to sprinkler valve?
