This APH I am working on has a functional quick-fire trigger. I will be connecting it to a bicycle brake handle attached to a handle below the stream machine. This will allow me to be able to pump and fire at the same time. I have surrounded it by other large water cannon to show the relative size of this beast. I have used a stream machine as a pump due to its excellent handle and ease of replacement. Also who else loves the irony of a stream machine slaved to a Super Soaker?

^Now that's how you introduce yourself. Welcome to WWN.



I would have gone for a more comfortable reservoir... but hey it'll get the job done. Also, let me be the first to invite you to Frozen Fury, the weekend of November 29th in Connecticut.

My God.... I envisioned that 2 years ago...

How does it work? Seems like a neat firing mechanism. You pull the soap pump inwards, and water comes out the quick-connect right?

Yes the Purell dispenser pushes the check valve and the water comes out the quick connect. The picture and diagram I drew above show the interior mechanism. I had to rotate the picture because it kept getting cut off.

It took me a bit of time to figure it out from your diagram, but basically you are using a backwards inserted check valve as a pull valve (well push actually) that is ingenious.

Wow. I like this guy, he posts good pictures and diagrams and everything!



So I have two questions. At the top of your diagram (as pictured) your o ring is floating (I edited to show this) and also there is this spring portion that I don't see the purpose of. Does the rod slide through the disc? The pressure should be enough to force the disc against the o ring, making a pressure seal. Is the spring just an original part of the soap pump?

Well the gold colored piece at the top is the brass check valve. The rod you asked about is attached to the disc which the o-ring is attached to. The rod is a guide rod strung in between two posts with a hole in each on either side of the check valve to guide the o - ring back into place. The reason that the o ring is floating is because the soap pump is depressed in the diagram which has opened the check valve by pushing on it's guide rod. The reason that I put the soap dispenser spring back in is because the brass check valve's spring isn't strong enough to close the o ring and force the soap pump back quickly after depressing. Also the soap pump is is much cheaper to replace than the brass check valve in the future.
