Q about pneumatics (please respond)(please)

[A-98]

ok im new to spud guns in general (i have only built 1 combustion) and im of a young age.

my question is: how do the diaframs (sp?) work? i get the bsic concept but i dont really know how to build /operate one (yes i have found articles and tutorials)...i think i want to go with the "floating diafram"


please respond to my account , this page , or burntfaceman420 (my aim)

thanks alot...


ps i want to build a gun like this one ttp://www.spudfiles.com/forums/viewtopic.php?t=136&

Guys, the spudwiki artical is basicaly operation therory, and basic construction. It doesn't go into detail as much as it should.

Personaly, I'v made 2 diaphram valves. One has issues getting it to seal - the pilot volume is tapered, so avoid that if possible - and the other sealed well, and had a sealing surface shaped like this. =[( (equals sign is the pilot valve, ( is the diaphram.
(the one that worked well was retired due to the use of a clean out plug.)

Information on bike pumps is in the wiki.

Yes, they sell PVC at home depot, and will probably have pressure rated up to 3 or (if you are lucky) 4". The fittings selection is rather limmeted and you won't find pressure rated things above 1.5" - which may or may not be an problem.
