After all the help I got from JSR and you people here, my airgun didn't work out, and it seems like I have a fear of compressed air inside any type of chamber now....However, I still want to make a hobby of a recreational activity that consists of using my brain to make a weapon sort of thing. By we...

I'll try that nick, and JSR TO THE RESCUE! Wait...washers can make a valve airtight?And I searched Google first XD

Any diagrams? Only thing Google tells me about is Valve Hammer and not hammer valve

That doesn't really help though..seeing how I need a flat seal...and thats for a piston..on a sidenote, I have no access to a drill press, although I can probably use a makeshift one by using a vise and a low/high powered drill. My previous, although failed seal, was a O-ring stuck to a piece of fla...

No, you provided good insight, no offense, but JSR just popped into my mind when I was typing it, explain more about the grooves,please?

Whats the best way to create a seal using O-rings? I need 3 seals made using O-ring as pictured below. Please help me JSR XD

Rag has a point, if I never found this site, I wouldn't have (re?)-invented the valve I'm working on now, and JSR and guitar helped a lot....too bad High School teachers are $@#$@#% and give out craploads of HW...

Just to satisfy my paranoia needs, if I have a 6 feet tube able to withstand 689 PSI, a 6 inch piece of that tube can also withstand 689 PSI, right?

Yea, I screwed up on the top seal so I had to re-epoxy, as you can see the bulge. I also had to cut out the 2 middle sections from larger pieces of flat epoxy I made. I might sand it all off later to give it a nice look. Theres also epoxy behind every seal so it won't fly off. R.I.P the pen I sacrif...

Umm..Can a mod put this in the right section?I'm not really sure where this belongs

Got one, but its hard to control it to cut it through the metal, it scratches up the metal a lot.

Not the problem with money, I can't go to a store that sells it >.> Only 99 cent places around my neighborhood, and I don't got a car >.>. PSI matters, cause I ain't pumpin' it with the bike pump anymore, I'm using my dad's car tire compressor, and THAT has a gauge

After my ghetto airgun project, my bottle popped, and now, every time I pump the new bottle, I think of my last one popping, my pump has no PSI gauge (bike pump), anyone know whats the PSI rating for a ginger ale 2 liter bottle?

Have something similar to that a home (but mine can cut steel, BOOYAH), it makes really rough cuts and it bends the metal too, one side goes up, another goes down
