Looking for a summer project?

Post stuff here pertaining to non-spud related projects that many forum members seem to enjoy. Hovercrafts, dirt bikes, electronics, propane-powered bikes, go-karts, etc. This is more of a project area,
not a place to chat about what you saw yesterday on TV. Remember to keep it within the forum rules!

I stumbled upon a website last night, after Googling for water cannon.
Seems that <a href="http://www.sscentral.org/">SS Central</a> is a forum where mebers discuss how to modify Super Soakers, for increased performance.

There's a lot of info on these modifications, but the post that caught my attention was: <a href="http://www.sscentral.org/tech/homemades/aph.php">The Air Pressure Homemade</a> , by Doom

I thoroughly enjoyed reading the entire article. Now, although there is a disclaimer:
<b>All content on SSCentral.org is Copyright © 2001-2004, the Super Soaker Central project, unless otherwise stated. All rights reserved</b>...

The article stated ( quoted from <b>Construction</b> ):

<blockquote id="quote"><font size="1" face="tahoma,verdana,arial" id="quote">quote:<hr height="1" noshade id="quote">
The design is 100% customizeable.
<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

I'll admit; I'm pretty lazy!- Although the design has an onboard pressurization system (homemdae pump, using 1/2" check valves), I think that the design would be more compact (as well as a lot easier) if you were to simply add a schrader valve:

<img src="http://img.villagephotos.com/p/2003-9/398596/customized.gif">

Pressurization could then be accomplished via a simple bicycle pump.

Now, before anyone has a cow, I relaize that the design utilizes DWV Bell Recucers. Personally, I would feel comfortable pressurizing this particular design between 50-70psi max. But that's me, not you.

I take no responsibility whatsoever if you get silly, and try to overpressurize this type of design. And I would highly recommend that the Bell Reducers be swapped out for pressure-rated 3" Couplings.

And seeing as how most 3" PVC pipe is pressure rated at 260psi, can you even begin to imagine the stream of water that would blast out of this thing, if you were to add a 3/4" BRASS Ball Valve, and an onboard CO2 system? -Definitely overkill, and I would not recommended pointing at anyone, but it would be pretty powerful for non-living targets!

As a side note;
I give full credit for this design to "Doom", from the SS Central Forums.8) And I have <b>not</b> built, or tested one of these yet. I'm merely passing along a great idea.;)

haha thats sick! I have been looking for a way to build a better water gun. I saw the one built by Dhall, and it was cool... but not quite on the same level as spudguns (if you know what i mean).

This one is more like it!

I just realized that there is a major flaw in my modified design...
Once the water level was at the top edge of the 3/4" elbow (plumbed into the 3" Bell Reducer), the air would simply rush out.

You would have to run the 3/4" PVC all the way through the 3" x 1" reducer, and cut down yet another 3/4" elbow, so that it would draw water from the bottom of the reservoir:

I had an idea for a watergun similar to that last week (inspired by a flamethrower of all things!). It had vertical tanks instead of horizontal ones and the pipe that sucks up the water would come down the middle of the tank to the bottom of the tank. Air would be filled by the top of the tank and water the same way. The air would be on top and the water on the bottom (duh!).

Edit: Post removed.

I'd suggest people intrested in this also try to build there own piston water guns. Take your current pneumatic, put in a barrel with internal piston and nozel at the end, and you're good to go.

Don't do what I did!

We were going on a rafting trip down the Wenatchee River.
The water is cold.
I had a wet suit.
The word was there was lots of water fights on the river....and I didn't think much of getting doused with cold river water as I have spent most of my working life on the water...and when I get wet I'm usually getting paid. Only this time I was paying to get wet....not my favorite thing.

So...I filled up surgical tubing pre-installed in my wet suit with a suitable on/off clip provided by a local hospital and a nozzle from a modified pen.
So we come to our first water fight and I poked the pen portion out of my wetsuit about in the pelvis region.
I begin spraying the enemy with much success...but after all the rowing and moving around I musta weakened the tubing and it broke!
As the water pissed out the surgical tubing, it grabbed all my short hairs and folded me up in to a screaming pile on the deck of the raft.
The young female raft guide freaked cause she thought I was having a heart attack. Her first aid training musta been somewhat limited as she was mostly interested in giving me mouth to mouth.
My wife was opposed to that treatment...besides, I was screaming like a girl. I think my wife rather enjoyed the moment whatever the cause?

I couldn't catch my breath to tell everybody what was wrong but as the water pissed out the tubing which was about 30' long was grabbing everything....and I mean everything,...including the "Thing"!

Finally...I sqeeaked out "surgical tubing".........and they unzipped my suit and proceeded to untangled me from the Python grip.
I untangled the "Thing" on my own.

Ditto, except it might be like something Draculon said, and pop into my mind when I don't want it to. Good thing I've got four days off work to get it out of my system.;)

I would personally just build something like D_Hall's Uber Soaker, except with multiple PVC chambers strapped into a backpack and hose nozzle, with regulated HPA pressure input. An extra 3" low power water balloon launcher strapped to the side of the nozzle assembly would make for a good waterfight weapon.:twisted:8)

DR is one sharp guy hes right on the design of the watergun on ss centrel its pretty lame
with DR's flaw fixed his design is nearly perfect I just think the tank's inner piping should go back further cause you tend to tilt waterguns up for the arc of the water stream and the water falls to the back of the tank

I think their should be an esaier way to refill the water
