I was told the bends wont matter now I have a QEV and slide valve.

Ahaha xD
I know, I'll probably be probably be pumping it up to around 150 psi on average using a bike pump If I'm impressed with the gun, and all is well, I'll probably invest in an electric tire pump, you can get some pretty heavy duty ones

The knob is a T-bend connected to a pipe cap with a Bicycle valve
And the chamber connected to port 2 will be attached to the tank. It will only be attached, they're not connected.

You tried epoxy?

Aha
I mainly just neatened things up


Thanks for the help

I've updated the design only a little, but what do you think.
Constructive criticism and ideas welcome
Oh and I'm new to pneumatics, go easy on me

Yeah but I don't want to have to refill every few seconds.

I've almost got it all sorted
I'll post the plan when i'm finished

Thankyou
So I basically need to change the whole gun layout?

Okay, but about the QEV and slide valve combo how and where would I set it up on my gun? Soo confusing

Thanks, I'll try adapt it but atm i'm not sure how to use a QEV :/
I suppose it's not exactly economical with the air, (If that makes sense! )

The extinguisher is around 35 cm x 12 therefore you can get an idea of dimensions, It's only a rough kinda diagram. I have two ball valves to make it kind of semi-auto. The barrel size is 15mm and the rest 22mm.
Constructive criticism is fine. I used paint

Thankyou, I'll try using the epoxy method.
Roughly what PSI would you estimate the epoxy could handle holding before giving way?

So I'm making a pneumatic gun using an old fire extinguisher from the tip/dump. I managed to disassemble it okay but when it came to finding the right fitting, i'm clueless! I measured the diameter and the ID is 28mm. I looked for fittings of the internet and it came up with BSP fittings. I went to ...
