My pnuematic paintball gun, now with breech loading.

Unread postAuthor: SpudBlaster15 » Thu Jan 18, 2007 8:02 pm

This is my pnuematic paintball gun. I posted a thread detailing the gun prior to the breech load modification, but it was hijacked. So I will post it again.

Specs:

Chamber: 1.5" x 14"
Barrel: .685" x 47"
Valve: 1" Modded Orbit watermaster
Pilot valve: Blowgun modded for better flow
Filling: Brass Threaded Schrader valve
Guage: 0 - 100psi
Loading: Aluminum sliding breech sealed by 5 o-rings

The gun (not rifle!!!)

Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

5 orings... well, I had 5 orings laying around that fit the pipe, so why not? :P It may be overkill, but oh well.

The pipe is 1/2" SDR 21 PVC.

People often refer to smoothbore guns as rifles, and the incorrect depiction often irritates people, including me and (apparantly) judgement_arms.

You need to do the .45cal bullet shell mod to your schraders cap.

Well we used to have dial-up so we had lots of cd's, I shot them with a crappy ghetto burst disk gun and it was SO COOL!.

They shatter into a million pieces and little bits of shiny foil go everywhere.

I actually live right next to (~200 meters away) from a firing range, so I could probably find thousands of bullet shells there after the 6 feet of snow blanketing our region melts.

BTW, does anyone else use thread in schrader valves? From what I have seen, everyone uses those pop in valves. I used one in another (ghetto) gun and it leaked if I took it past 60psi.

I use pop in valves in my soda bottle chamber, but I mount them in the bottom like in the diagram I posted here (my post is halfway down the page) http://www.spudfiles.com/forums/viewtopic.php?t=5332&

I have taken it to 100psi with no leaks whatsoever.

Same here, not many people in Australasia area can find threaed schraders.

@Spudblaster ~ You can use 9mm shells you just need to dremel down the cap and possbily epoxy it in.
