[update]Killa's amazing barrel sealer!

Unread postAuthor: killagorrila99 » Wed Dec 20, 2006 4:52 am

Here she is! First time I fired it I had my doubts, It was at 20psi with a marble. I pulled the ball valve and CRACK. But I never even saw a blue flash in the muzzle. The marble left so quick, I am hesitant to try a 300psi shot. UPDATE: longer barrel.

Woah! :shock: Thats a pretty awesome gun :twisted: Pity large dia metal pipe cost so much, as if the pvc was metal it would look heaps better, try painting the pvc with black zinc sparypaint,it will give a heavy, solid, metal affect to the pvc and make it look metal.

I love that you use a B. Very good gun but why not use the chamber from the hunting rifle? I believe that the blue flash was the marble.

Yeah that is nice but how could you take it to 300 psi with pvc and thats a rubber schrader which might not hold 300psi. How would you pump it to 300 psi anyways?

Heh... do you ever wonder WHY they rate it to 1/3 it's <B>calculated</B> working pressure?

Because that's all it is: a calculation, followed by a series of simple and uncomprehensive tests to see if they were right. Not flaming you, just saying I wouldn't trust the black hearts of whatever pipe corporation made your chambers pipe and components with my life.

Nice overall gun design though. I love barrel sealers.
