So neoprene smells, eh? Okay, but just incase I need a little help on something, it's okay to ask, right? I hope this turns out well, and if it does, hehehehe...thank you guys, you're such a big help. I wish I could just give each and every one of you a hug. And no, I am not gay. I'm just very appreciative that you guys help me. Yea...a little too much thank yous...but yep, thanks!

HA HA U MUST B GAY LOL11111!1

Seriously, though, thanks for the gratitude! (Something some members seem to lack) Oh yeah, You should check out the Spudfiles wiki. It'll definitely help in development. Heck, make an edit with what you learn from your build!

Umm, must have been about April last year.

Since then i've put together quite a few pistons, not all have been used. The biggest would be a 3" one, which hasn't been used yet, and the smallest would be a 1/2" one made from two 9mm bullet casings.

just make sure everything is pressure rated...

you don't want this:

These were after a 115 psi shot (it blew up... obviously) :?

April last year? I thought it would be like...5 years ago. Hehe, and that's pretty scary, LynyrdSkynyrd. I don't think the fittings are pressure rated in Home Depot. =|

I've only been spudding for 3, of which only two has been spent here.

Technically I made a piston in October of 2006, but it wasn't anything i'm proud of, so I disowned it :D

Lowes has some pressure rated fittings up to 2" i belive.

sometimes you can get lucky and fin sced. 80 fittings for sprinkler systems. Though stores aren't really consistent with that stock.

lol from an engineering standpoint you always can improve on something in someway.

That last piston of mine was the predecessor of my new cannon's pistons. The old valves worked, but thats about it. They weren't anything special.
