SpudFiles

Hi all this is my first post, but not my first build. It has been quite a few years since I have attempted an air gun of any sort, after looking around spudfiles and seeing one of JSR's how to's on a $20 QEV valve I thought I would make myself a plinker.

The 166hand stands for 16gram Co2, 6mm barrel bore, and handheld. I wanted something simple relatively cheap to build and cheap to fire, I am still yet to test out the barrel I am waiting for the Epoxy plug to cure before I even think of firing it.

If you havent already picked up the handheld is powered by a 16gram Co2 bike tyre inflator, which is attached to a slide valve purchased from Ebay, which is then connected to a QEV valve also purchased from Ebay, and the chamber is a piece of 20mm chrome plated copper pipe 150mm long, the barrel is OD12mm and an ID of 6mm.

I am going to attach a trigger to the slide valve and a spring to return the slide back to its original position, this is going to need some tweaking to get the correct spring. I also may make a shell for the handheld if I am happy with power.

I have attached some pictures and will post more as soon as I get some ammunition and the barrel epoxy cures.

massive chamber you could cut it in half other then that its really good.

Looks promising, and it seems the components have no issues with unregged CO₂ from a small chamber.

A simple tee magazine should be a doddle to make.

This is just the sort of thing I was hoping the "under $20" post would inspire

I wasn't sure on the chamber I will get a smaller one tomorrow.

JSR the bike inflator is a regulator I'm not sure on the psi output I may add a T piece in and attach a meter. And I was thinking of using an empty Co2 cartridge as a magazine mounted above the barrel with a strong magnet bellow to hold the ball bearings from rolling out the barrel.

Since my original post the handheld has developed a few leaks I think it's time for some JB weld on the threads I don't think Teflon tape is withstanding the freezing temperature of Co2...

Ahh dam I didn't know it was reg'd id check the pressure.
