On top of it, injecting a stoichiometric mix into a chamber that already has air will result in a lean fuel mixture.
If you want a mix of 4.5% you will need a higher percentage in your bulk tank, as your chamber is already filled with atmospheric air.

If I would do something like that I'd machine my own.
I'm talking your style here, combining objects and epoxy.

How can a hacksaw be complicated?

A typical combustion guns only get up to 60 or so PSI. A tight fitting spud might have 10 or 15 PSI equivalent in static friction (especially with a double-beveled spud cutter). Figure dynamic friction is a fair bit less but probably still significant. Its not just that dynamic friction is less, on...

Which is why the over/under layout was developed. Having your chamber parallel with the barrel instead of inline behind it, you have a more powerful one gun or a shorter one with the same power. Or a bit of both.

The propulsion force acting on the projectile is so large that the friction force can be ignored.

Looks good.

What is the "bottle" on the intake pipe?
If it is obsolete it could be removed.

Bullpup allows for a shorter gun or a more powerful gun in the same length. Without bullpup you are basically wasting length on stock that could've been used for more barrel.

In my opinion, bullpup is the way to go in the future.
Not only in spudding, but also in commercial air rifles/firearms.

Combine a quickconnect with your epoxy.

Hmmm
Stuff could get interesting here.

Yea, I figured it would be fun to beat you to it by using italic.

Open up a quick-connect fitting. It works just like that, but then with balls instead of a rod.

Im there. But you already knew that.

I know it will be better.
Cool the oil!

A fridge compressor? It looks like an electrolysis machine to me...

Stop doing stuff with water. Its dangerous in your hands.

Nice one on the seals :lol: Looking at how you like flying brass you must really hate revolver type guns, maybe even more then seals. Why not just actuate the cartridge mechanism with a pneumatic ram? Mix up poland's semi with your cartridges. Then slap on a popoff or something like that to make it ...
