Hello farcti! This spectacular this! Very good aesthetics and as always, a neat construction. I like it!
With what pressure does this weapon fire?

[farcticox1]

Only 140psi, it's just standard pneumatic parts and PVC chamber, that is enough, it will go through 1/2" plywood.

[hectmarr]

Surely, I mean, that's enough. Actually to do serious damage to other harder materials, the most effective, simple and elegant and least expensive, is to use the other type of weapon, of those that should not be discussed here for obvious reasons. Very nice that you made. Regards!

Nice build and great WIP pics.

I will be making another video as well when the weather warms up and I can get back out in the workshop again.

Dude, that magazine system is so cool it's ridiculous.

The whole thing is awesome, obviously, but that mag... Rube Goldberg meets Machinery and it works!!!!

[farcticox1]

It started simple in my head, then got a bit more complicated, but it does work nicely.

Tested my chrono device, it shows a consistent 416fps at 140psi. 10mm steel BB is about 4.5gms/69.4gr.
Muzzle energy = 27ft.lbf/36joules.
I'm changing the PVC chamber/stock for a stainless one, it has less volume but I will feel safer taking it up to higher pressures. Going to do the same chrono test when I get it assembled again.

New stainless chamber. I like the adjustable stock better.

The results are in, new chamber at 140psi = 357fps, 160psi = 385fps

I know this is an old thread but... Nice! It looks a bit like a vector...

Well spotted, that's the profile I used
