My new CPS system (Almost Done!!!)
Re: My new CPS system
YES! Just tested it. Super easy to move, and holds a really good seal! Now I'll just put on a duct tape handle and cement it on! I can't wait to get this thing going!
I'm also going to test it a little bit more.

Re: My new CPS system
Good to hear! What are you using as a reservoir? A solar shower in a backpack maybe?
Re: My new CPS system
A solar shower. 5 gallon. I'm not sure how I can fit it in a backpack. I have one internal frame backpack, but it would be kind of strange to carry that around. External frame backpacks are so expensive for teen like me. TBD.
I have completed the water gun! Except for nozzles. I have one drilled, and I will drill another later or maybe tomorrow. I just have to wait to 6 pm (Eastern time-same as New york city) tomorrow to let it cure. Too long to wait!

Re: My new CPS system
I reccomend hose barbs- pre-drilled, nice and smooth, longer, never lopsided... amd there are not a lot of sizes, but enough.

Beware the PurpleWell, not that much soakage.
Re: My new CPS system
I think I will try some of those.

I just want to make sure those clamps are tight enough. I don't want to pinch the LRT, but then again, I don't want it to fly off, either.

Re: My new CPS system
They look like they could be tightened more- cutting the LRT shouldn't be too much a problem with that duct tape.

Re: My new CPS system
Okay. My dad just made me extremely cautious about cutting the LRT. Maybe one or two turns?
Re: My new CPS system
I used a 20l (about 5 gallons) solar shower and I just used a normal 25l backpack and cut a hole in the bottom of it which I reinforced with a rubber washer. I added a small isolation ball valve to stop it from leaking when disconnected. I have recently added some quick hose connectors as well.Fishfan wrote:A solar shower. 5 gallon.

If your worried about cutting the LRT you could add a little more duct tape.
Re: My new CPS system
I put about 3 layers of duct tape. Is that enough?
Re: My new CPS system
It should be, but it's best to check (tighten the clamp, and if it looks like it's digging in too much, add more).

How does it look now? Should it be tightened more?

Re: My new CPS system
It should be all right, it depends on how long the bolt is.
Re: My new CPS system
Its about an inch long. I put the clamp directly over it, I did it by feel. Anyways, I'm going to test the water gun in precisely 6 minutes! I can't wait!
Re: My new CPS system
At only an inch, and based on how far from the head of the bolt the clamp is, I wouldn't put a huge amount of faith in it. The clamp is only holding onto the very end of the bolt, and doesn't have to go far to come loose and fly out under pressure. You could remove some of that extra LRT on the inner layer to get the bolt further into the tubing and give the clamp more to bite on.
Re: My new CPS system
Well, we will see how it goes. I won't have my hopes too high, but right now I just want to see if it works. Wish me luck!
Re: My new CPS system
Good luck! Just don't put anything of value behind that bolt in the LRT until you've full pressurised and de-pressurised it a few times.
Re: My new CPS system
Thanks!
Re: My new CPS system
I've fired it! it works really well, except for the fact that my nozzles suck(I get a very rough stream, not laminar at all), and there is a slight leak around the bolt in the LRT, and the pump slightly leaks. But even with bad nozzles, I still get about 35-40(guesstimating) feet. That is better than my scatter blast, the best water gun I have other than my homemade. Also, I noticed that it is bulky and awkward to carry around. Aldo the plastic ties scuffed up my arm, but maybe some electrical or duct tape around the sharp edges will fix that. I think I will have to get different drill bits, work on my drilling skills, and seal the LRT. I think I will use a hose barb and a an endcap, because my dad said it is difficult to seal around a bolt.
Re: My new CPS system
Some pics of the full thing from each side (with and without PC cover if possible) would be nice. Firing pics would be even better!
35-40ft isn't brilliant for a homemade (probably down to the nozzles) but as that's a guesstimation, it may be more like 50ft, you never know.
My most effective nozzles are the hose connectors. They offer a smooth change in diameter rather than an abrupt change. For smaller nozzles try (as atvan suggested) hose barbs, if posssible with a smooth transition in internal diameter. You could use those things SEAL used in his nozzles in his SCH.

Re: My new CPS system
Well, I measured to how far I got, it was 37 or 38 feet. Anyways, that doesn't matter right now, because the two inner layers of the LRT popped. I know exactly how it happened. When I was trying to get the bolt in farther, I was trying to screw the bolt in, and that twisted the inner layer of the LRT. When the smaller layer popped, the sudden pressure popped the second one, although thankfully the outer layer stayed intact, keeping me dry. I guess I'll just have to order some more. . This time I'll order 2 feet of each. Next time, instead of a bolt, I'm using a hose barb and endcap.
About the hose connectors, what are those? I know of hose barbs, but not hose connectors. Could you give a link to one from Lowes or Home depot?
