Great gun mate.......i checked out your other spudgunning videos on youtube and you seem to me following spudgunning more than just a hobby! all your designs are beautifully machined! Keep it up, and you really should be proud of this little beast!

Save up for a $20 valve? Man I'm glad I'm not a student anymore

University? xD

Why not just get something like this ? It should happily take 500 psi without failure and will likely be more compact and efficient, as well as much cheaper. i still havent decided which valve to use ....the qev definitely will do the job + its free shipping outside the US so i might consider that ...

Too right mate but the problem is sprinkler valves dont hold that high pressures while im too lazy to make a piston! But ill probably order a 500 psi sprinkler valve which i am getting off a local dealer!!! Cant wait for my new valve..... 500 PSI + Sprinkler Valve = Carnage xD http://i1091.photobuck...

Ok, I have Uploaded Some Damage Pics For U Guys to see the damage a Sch 80 Rifle Can Do......all Shots were at 200 psi! I have also build a metal cannon on recommendation of some of the spudfiles members earlier in this post so u can check that out too! http://i1091.photobucket.com/albums/i392/Sch12...

Ok guys i have completed my design for the metal gun ...i will upload some pics for it ......next thing to do is make a spring action for it!

LoL....Feet Per Second !!!! Ok People taking suggestions from the above comments i have decided to remake another model! It will Be Of the Following Specifications: Construction Material: Sch 40 Galvanized Metal Pipe Chamber Length: 6" Chamber Diameter: 2" Aprox Volume: 25 Cubic Inch(Half Of This Ca...

Good design.....it would look even better with a good paint job and some accessories like laser attachment or sight! By the way wht is the performance on this desing???

oh ok.......ill update u on a new reading tomorrow probably!

It is impossible to get that velocity using air. It is most likely a reading of the muzzle blast. Sorry

Whats muzzle blast???

So With a 20 cubic inch metal chamber with 200 psi would i expect better results than a 40 cubic inch metal chamber at 100 psi?




This is a reading of 0.2 gram bbs at 220 psi!

scheduled 80 isn't a pressure rating but the wall thickness, just to make sure did the PVC say nsf-pw then the pressure rating in psi, or pn and the rating in bar? anyway i still don't recommend using any PVC part at pressures above 120, they might be able to handle it but if it did explode the pvc...
