Thanks, Sorry, the news was on in the background, in the end I wrapped it in tape and poured epoxy over it, I usesd JSRs tip with the drill bit wrapped in tape on the end end to keep it centered. This is actually the second attempt with these parts, the first one was a few inches longer but when glued the barrel sagged so i dremaled off the end and tried again.

Lookin good there!
After seeing the multitude of pen guns posted in the last few weeks I decided to try building one.
Lol, yeah...what is up with pen-guns gaining popularity like crazy all of a sudden? (I'm guessing JSR is behind it somehow) :D lol

Thanks, MR. Sandman started it then JSR, now mine, and I think Gun Freak and JSR are both planning future ones, Lol

Or mine cough cough. Just kidding. Jsr started it a while back, then it was Rcman5013, jook13, then sticky tapes then my old one. I guess mine just re-stirred things a little, but the original concept of a pengun is Jsr's idea.

I only wish my attempts to do the same with hybrid launchers would work as effectively as this. :roll:

It would be cool to have more hybrids around but pen guns only cost about 10 bucks to build and a few hours max unless you machine the piston

Maybe I'll build a 30X hybrid pengun. :D

But yeah, small pneumatic launchers have the advantage of being extremely inexpensive and simple to build. In terms of popularity, such a design will win every time.

Funny enough me and gun freak were discussing a hybrid pen gun yesterday, hybrids still win in power every time though.

It would be difficult to pull off a working hybrid pengun and maintain the inconspicuous, pen-like appearance. This is a situation where a premixed bulk tank containing air/fuel mixture might actually be a good idea...

If my own small hybrid experiments are anything to go by, I would tend to agree. A piezo or hot wire ignition system could also conceivably me made small enough to fit in a pen sized package.
