If my friend got injured I'd quit this hobby.

My friends gun blows up right in front of me and I only have one thing to say...ROFL!!!!!!!!!! That had to be the funniest thing ever. His fittings were leaking so we replaced them the other day, I told him to wait 24 hours for the glue to dry but he thought 20 hours would be long enough....so we pu...

Can the piston being too tight be the problem?

Sorry, deleted this.

Alright thanks guys, I'll have pics up tomorrow.

Thats a good idea

Read edit Alright, so I'm looking in my garage for some junk for my cannon and I see this box full of old plumbing supplies. I look in it and find this thick rubber toilet sealing thing covered with brown stuff lol, so I cleaned it up and put it on my piston and it works perfectly. Here's the proble...

This is my 1st Pneumatic, I would like to thank everyone on spudfiles for helping me. DPS-1 is a simple pneumatic made with Sch 40 PVC and a modded Sprinkler valve. I know the valve should've gone on the other side but I didnt' know if my fittings were pressure rated. Chamber- 2'x4'' PVC Barrel- 5' ...

Great Idea, I have an electric flyswatter and never thought of that.

I looked at the 1st one before. I just looked at the 2nd one and that answered all of my questions. Thanks, I've been looking for that for a few days now.

I was wondering if I turn this valve right (+), will it allow me to pump up my gun to higher pressures? My gauge isn't working atm so I cant...

I finally understand how pistons work. Thanks.

OMG I LOVE YOU GUYS!!! IT WORKS!!! I sealed the guide rod and lost the hose and it works perfectly now. I had a competition with my friends and my gun shot the farthest! OMG TY SO MUCH!

Pics and vids will be up in a few days

Ill do that right now, thanks so much
