The abs plastic is actually leftover shelving from a grocery store where I work. Can u say free? I had a detent on the barrel, consisting of a .177 cal bb protruding into the barrel, and in place by some latex tubing over the barrel. For some reason this seems to smash the crap out of the bbs, and t...

For a piston in a 2'' coaxial chamber, a simple rubber cork can be used.
nothing like a 1 piece piston, made of solid rubber.

here you go, less than 3 bucks for 1.

Here is another photo with a cloud chamber attached. The Pop of valve pulses the air, and further agitates the BB's. Ive found i get 2-3 BB's per pulse pretty reliably. This is currently 6mm, and hold about 50 bbs, but i do have a .177 barrel for it as well. http://img535.imageshack.us/img535/3896/k...

Let me explain jailbreaking a bit more. By default, apple phones can only install software that has been digitally signed by apple. People who write apps, and other software for the iphone, must have it "signed" or approved by apple, before the iphone/ipod will run the software. There is some VERY g...

If you feel like doing a bit of work for your phone... the iphone 4 is pretty good. However, in order to make the phone worth while... you will need to jailbreak it. once jailbroken, you can do so much more with it... such as use it as a wifi broadcaster, and get online with your laptop... using you...

Jeremy, again, we DON'T have decent pvc tubes here. Unless your homes and buildings are plumed with square tubing.... i dont see why you would have any trouble finding "tubes" You obviously have access to a CNC mill.... im sure you can find/get some tube stock.... The block looks great... the rest ...

[quote="jackssmirkingrevenge" Was that last one intentional :D[/quote] Sadly no. :shock: I made an assumption (Doh!) :oops: that a foot of ballistics gel would stop the round.... i guess a heavy stainless steel dart (1/4" diameter) traveling at high speeds is hard to stop.... haha Also, the 300-350p...

A burst disk would be your best option. Get a 2" PVC union...place it between your chamber and barrel. Use the union to hold a bust disk (a few layers of aluminum foil would be fine) and add pressure. Once you apply more pressure than your disk can hold, the disk will break and the cannon will fire....
