First, we have the Big Salvo pump and trigger assembly. I plugged the tubing that goes to the other 3 (nonexistent) tanks, then drilled out the side of one. There's actually a spring-loaded check valve in there, that gets pushed in by the trigger. It made sense in retrospect, but it's different from the hornet trigger. Hornets have double o-rings and such to keep the entire thing pressurized, allowing blast button use. This setup, meanwhile, means that after firing the first tank, the pump and trigger assembly become unpressurized, along with the first tank firing. This will be touched on more later.
This is the bladder container from the Iron Man Super Soaker. As it turns out, 1/2" CPVC slides PERFECTLY into the plastic clamp. How nice!
I have 1/4" OD vinyl tubing running from the CPVC tee, back to the hole I drilled out in the trigger assembly. Something small, that gets the job done. Also something I can run on the outside of the blaster for later modification.
After assembling, sealing everything, and securing the tanks into place, we have this thing:
As of right now, thee's a leak I need to fix. Also, due to the fact that the trigger assembly itself depressurizes, I lose a ton of air out pf the bladders with each shot. So at the moment, I get 3 powerful shots. AFter fixing he leak, it'll help a bit.
However, the next major step is playing with the tubing I ran outside (and the tubing to the BS tank, I have a hole cut in the side for access, done after these pictures). I'm going to install a check valve at the base of the air line, so it won't leak back with every trigger pull. Secondly, I'll run a tee of that hose, put a magstrike button or some other valve on the grip, then run it into another tee on the BS tank line. Not sure if that was clear, but you get the idea: stop leaks, use my free hand to repressurize the tank, and fire at will. I'm gonna guess 6-7 good shots out of that if I get everything sealed up correctly.
