This is the first mini and the first coaxial pneumatic that I have ever made so I appreciate any and all comments (also this is my first post here so hi to everyone).

I have not glued anything in yet, so I have only been able to bring it up to around 30 psi (with it all taped up and even then there are a couple of leaks).











inonickname, thanks for the help.

Looks good so far, pop the pictures up and tell some specs..such as operating pressures etc.

i would suggest keeping this at low pressures i have had pill bottles explode when making mini combustions let alone a pneumatic nice job tho

im guessing the schrader is also the pilot valve

*smacks for head* why didn't I think of that? Of course, a mini coaxial. Mini pistons a lower pressures should be easy right?

Great looking gun mate! Pneumatics can be much more dangerous than combustions... A pneumatic has stored pressure, whereas combustion has a spike of pressure.

Stick to 30 psi

Still, nice first effort, now buy some proper epoxy and make yourself a 400 psi mini coaxial

Sorry for responding so late I have had some homework trouble. I am going to try and get it all epoxied up this weekend. Also I was wondering if wrapping it in some thin rope/whipping line and then epoxying it would increase the max psi that it could hold.

AFAIK it would. But it would be expensive, and I don't know how much extra pressure you would get out of it...

Looks like it's a common hard/brittle clear plastic body with a softer/elastic plastic cap.

Reinforcing it wouldn't be too easy, when you wrap with string it doesn't add strength in all directions. You'd end up with it in the middle of a ball.

Easiest to just leave it as a low pressure pneumatic for desk plinking and make a separate one if you want higher pressure.
