SuperCAP uses compressed air to force water through the nozzle. It's plain old air though. Using a liquefied gas like carbon dioxide would be more space-efficient, but you can't use PVC anywhere – as gas vaporizes (going from liquid to air), it absorbs heat and chills the entire structure down, whi...

If the larger seal only does its job when the valve is completely open, what seals that hole the rest of the time? And if the valve is sealed the rest of the time, why does it need extra sealing power when open? The spring isn't pictured, so I thought it would be outside the valve. Sorry. Anyway, it...

You can't use a wire there because it has no compressive strength – only tensile strength. A rod would work better here because you can push the other way from the outside and close the valve again.

I'd just use an O-ring sliding in 1/2" PVC.

Why do you have two seals right now?

I would also caution you not to write off every Canadian Tire store in the world. What these guys did is hopefully not too common, and I remember the franchise was selling CPS-line water guns as recently as a couple years ago—so they may be useful in the future.

Only if you need to. For a given water gun, there's a maximum pressure that it'll reach. There's a pressure at which something will break. And there's the pressure that the safety valve is set to. From what I know, constant pressure water guns have a quick ramp-up to high pressure with the first pum...

Send them an email and see what they say. B)

Ooh, those arrows help a little. And the picture of the Hydro Blitz valve assembly helps, too...I'm seeing why cantab suggested a similarity in the thread you linked to. In the Tiki picture, there's a metal rod that goes off the bottom of the window that matches the black rod in the Hydro Blitz pict...

Does the SS 60 have a pressure chamber separate from the reservoir?

iSoaker, this page doesn't load.

CPS 2500: Open it up and see what's wrong.

SS 100: Are any tanks, tubing, etc. cracked and leaking? Or is it just cosmetic? At any rate, putty epoxy should do the trick.

Good luck! B)

No, you can get as little as one foot (30 centimeters) of latex rubber tubing at a dollar or so per foot (depending on the size, of course). If you're outside North America you'll have to order from a manufacturer or wholesaler. It would be easier to mod the Flash Flood's trigger mechanism than to m...

Teh_Moron, even a perfect tank wouldn't be able to chase somebody, go through a doorway or shrubbery, capture a flag, etc. If you play RTS games you'll see that there's a rock-paper-scissors mechanic relating infantry, light vehicles, armored vehicles, anti-tank, buildings, and artillery. Even in re...

I think McMaster-Carr will ship throughout North America because of NAFTA, so bulk ordering isn't necessary. And you definitely won't need more than several inches of tubing, although getting some extra is advisable. There have been a couple co-ops before, and some plans for a more formal system, bu...

This is definitely a good candidate for latex rubber tubing if you live stateside and can pick tubing of the right size. Custom lengths, as much strength as you want, etc. You'll need to be a bit creative in mounting the bladder and finding a casing, of course.

Mobile pillbox, I see. My most immediate concern would actually be splinters. :p Teh_Moron does have a point, though...dodging works about as well as shielding for defense, and it looks like you have at least a few trees, too. Transportation and safety are a lesser problem than the fact that protect...

I've never seen a stock water gun with a bore over 3/8". Look at the pull valve on the page I linked to: the valve may be wide , but the hose doesn't surpass 1/2". A trigger for a 1/2" ball valve is no big deal; a 3/2" pull is what I'd expect to see, in a stock water gun. Homemades are another issue...

C-A 99, I much prefer Max-D triggers...the fact that CPS blasters are fun to shoot is another issue, and stems from their actual power. Max-D triggers : old triggers :: IBM keyboards : old keyboards. Max-D triggers also happen to hook up to ball valves, which themselves are more reliable and produce...

Wow, neat mod. I remember seeing a similar PC extension about a year ago...but the actual bladder wasn't replaced. The old was was simply allowed to stretch further, which would wear it down pretty quickly. This is better. Some of Larami's early patents , circa 1996, on water gun bladders addressed ...

This thread at Super Soaker Central might help. We've also pointed people to the the relevant forum at UKSGC, but that's mostly for general plumbing hardware, and not LRT in particular.

The green bar in the bottom right says "1991"...

The air pressure homemade and SuperCPS are both fine water guns if you're looking for a lot of power. They're both on the site that Ben linked to.
