this has been posted before i dont think its that safe,cool but not really safe.

even if there was a bigger chance of some nut pulling out a gun or a drunk getting trigger happy they sure as hell wouldnt get to far if their classmates were armed and you would have to be toatally SLAMMED to not think twice if half the class was ready to give you the dirt nap.Im all for it any ass...

this is an older pic of me lighting an antique zippo for the first time
not sure who the photographer was though.Yes i collect zippos.

its for n00bs they dont know.[/u]

Here is my little quiz should be easy for you guys to pass and should be educational for n00bs.post your answers in the topic and well see how you did! (shouldnt be a challenge for you guys.) a=i can use that! b=that will blow my face off! This quiz is assuming you are making a pneumatic dwv is fine...

Ok learn something new every day.

I have never seen NSF-PW pipe with grey text before.All pipe with grey text pipe i have seen has been DWV.

that pipe looks like dwv does it say NSF-PW?

No its not safe really its not.you could i guess but it would be a bad move.I have had dwv hold up to 80 psi but i was very lucky.im more worried about the pipe though i have never used dwv pipe just that one fitting.Fittings blow off but pipe explodes into shrapnel.

EDIT:Gah! you beat me.

AH! sthorne but you didnt listen.im not really that bad i just have a short fuse.

ah just make a piston valve itl save time and money.

ok but next time try and listen. You could put a gun made of pressure rated parts and put it inside this but there is no safe way to make it pneumatic.[/u]

See how nice we are here at good ol spudfiles? if you listen and follow the rules we can be great but if you dont...well you know.

LISTEN TO ME! YES IT IS SCH 40 BUT ITS NOT PRESSURE RATED!
Why cant you listen? its not that hard of a concept its sch 40 which really doesnt mean crap its not a pressure rating it has to say nsf-pw get it into your head.

I doesnt mater if its sch 40 thats just a thickness rating not a pressure rating! Its not pressure rated not the fittings not the pipe!
