Hi I'm new here, my name's Joseph. So I'm interested in a simple ball-valve spudgun, that offers multiple shots from 1 pumping. So--

What size/how small do you think an air chamber can be if I'm using light naildarts 45gr. And using 100psi. Anyway Im gonna use 1/2' pvc pipe, ball valve and this concept eg.

This would give me how many shots? & wouldn't the pressure get lower with each shot if you do this Will it get weaker each time you let air in the main-firing air-chamber. The large secondary chamber will feed the "first small chamber" with pressurized air, so I need to know if doing multiple shots this way will still gimme 100psi in the smaller firing chamber after a few shots.
And what do you think of the small air-chamber @ 100psi. Will it shoot a light dart really flat, I wanna do some backyard plinking at targets.

Unless you plan on spring loading the firing ball valve, it won't be powerful or accurate enough even for satisfactory plinking.

If you want multiple shots and good performance, I refer you to my recent demonstration, adequate even for those on a very low budget:

Its just a concept, I'll worry bout the accuracy and the way I fire the ball-valve smoothly. I know that using the full/big air chamber will certainly produce good results, what I'm curious about is the small chamber @ 100psi.
And if I get multiple shots from 1 filling with this method, will the pressure in the smaller chamber steadily decrease with each shot, or do I get a few full power/pressure shots? Thank you
I'm just starting out so something simple would suit me. Thanks again

Think this would work? Can a garden hose nozzle handle 100psi?
Is the high pressure hose idea good?
Sorry for so many questions.

I used one for 90 psi here.

There's a world of knowledge on this forum, why start such a primitive design when you can make better stuff for the same effort? Wise enough not to jump in the deep end, but don't walk over a puddle either

If you're going to use a garden hose attachment, might as well use a blowgun.

Blowgun + 100psi + reasonably long barrel = decent power.
