lol The outer tube is a bit smallet than that of a regular pen tube. What you see there is evidence of me smashing the top in to fit the tube kinda like pvc and a potato, except harder. 
EDIT: the video is now up. I slapped it together so it's not very good.  |

You should use a shock pump. beat JSR to it  |

| Well I use this because it is the only pump i have that can attach to shrader valves. My friend is holding my 250PSI mini compressor at his house so I can't use that until the weekend. The mini pump is very concealable though... |

| I was thinking about making such a pump. It would not be very easy. Creating those pressures requires a lot of force. I was thinking about making a 500PSIG stomp pump but then the bottom line came out to be too much, especially for a pen gun. It is also hard to make things seal at those pressures especially moving seals. That little piston in my pen gun took about 15 man hours to perfect. |

Here's an interesting thing. Compare my pen gun to JSR's. They are displayed in the same manner. I'll put them side by side to make it easy.

I read and read and couldn't find the answer to my question.
How did you attach the schreader to the chamber? It's very clean and I can't see any solder points or welding marks... |

| LOL!!! Good one. I think it looks great, but u might want to be more careful about dissing older members like JSR (even if it was subtle). Anyways, great gun. I like it. |

Right you are, had a hell of a long weekend
Very nicely done, I built my pen gun in a few days as a quick "must enter something in the contest" project and there was a lot of room for refinement, glad to see someone made the effort 
As I always say in these cases though, small volume and calibre needs high pressure to be effective, I would definitely invest in a shock pump or similar |
