i wasnt sure wether to post this in the pnuematic or mini section but here goes.
i havent posted many guns for awhile bc i have been missing pictures until recently so i will probably post a couple more today. i built this about 5 months ago.
the main chamber is made of 1/2 inch copper pipe
the rear section is 3/4in copper (too fit bike valve for i cannot find a screw in)
the barrel is 1/4in ODcopper pipe
it shoots .177 steel bbs
its not amazingly powerful but whatever. ive only taken it to around 120 psi

Nice little mini there, although a bit of sandpaper and paint never hurt :D. The only thing that concerns me is the schrader valve. How exactly is it attached? Other than that great job and higher pressures and damage pics will make everyone happy.
Yeah, it's that important.

That didn't really answer my question. What I meant is, how is it secured into the adapter, that schrader isnt threaded.

To solder you need heat and heat just kills rubber... I hope you soldered it before you inserted the schrader.

btw. the piston could use some sand paper too :D

its an old school tire valve that you have to squeeze through the back of the endcap. it works for me :?
