Fairly new here, although i've been looking through countless threads and pictures looking for help in designing a launcher. I've decided on using the "Toolies Valve" design, and i have a couple questions.
First, will a Toolies vale work in this kind of set up? Im looking to create a lightweight, relatively short distance (100 or 200 ft) launcher for scenario airsoft, designed to take out small buildings and bunkers at my local field. I need something to operate at low- medium pressures (50-100 psi), that can be filled either by a normal air tank, or a regulated HPA tank. Here is a diagram that i drew up:
(Not to scale, just a rough estimate on how i'd like to have it laid out)
It's going to be filled via 1/4 male quick release with a ball valve for on/off, and piloted by a a blowgun attached to tubing on the back that's going to be routed up to the top of the launcher so it can be triggered much like the real one, i didn't draw it because my questions are in regards to the valve/ body of the launcher.
I guess we'll start with the piston itself. Would something like this (see below) be adequate? it seems that all the threads i can find are dedicated to coaxial guns, so i wasnt sure if the piston design would be able to transfer between the two.

Finally, i'd like to keep the overall length of the launcher at or a little over 2 feet. Any recommendations on chamber vs barrel length? From what i've read, it seems that the valve is more important than the cb ratio, but i'd like to try to get the max amount of efficiency out of this thing as possible, which is why i bring it up here.
