Mini pengun

Miniature guns are novelty custom, unique, and sometime downright crude! Common construction materials often include pill bottles or pens. Show us your work!

Hi everyone! I've been a lurker and might as well post something. :) This is a mini coax based on jor2daje's pengun. It has a solid rubber piston, 1/8 brass tubing for the barrel and 7/32 for the chamber. I don't have a shock pump, so it is crap at 160 psi. Btw it's my first build and I'm surprised that it actually works. :D

Looking good! Penguns are fun, especially with >400 psi :wink:

You clearly did your research on this one. Congratulations on getting it working. Welcome to SpudFiles :occasion5:

Nice first effort :)

Probably just as well, if the breech isn't reinforced the piston will probably dig into it.

Have a read through this thread: http://www.spudfiles.com/forums/pneumat ... t7858.html

Update: Well, it developed a leak (must be the poorly mixed epoxy) so I drilled it out. How do you reinforce the breech?

See if you can find some tube that slips over the end of the barrel, basically what you want to do is spread the contact area between breech and piston.
