Re: Homemade Splashzooka

Hey Tyler,

Nice work! Where did you get that nozzle? I'd like to buy one and try it on my rig.

What diameter cocktail straws did you use? 3mm? 4mm?

Re: Water spray gun for garden hose with laminar flow???

Hey Simon,

Yes; that is what I was talking about. Item 43a only.

However, you could further improve the stream by adding laminar flow elements before the brass sweeper nozzle. You just need to include a female garden hose adapter as your connection point for the garden hose.

Hi Loeve,

Try the Sweeper Nozzle that I used here (item 43a on the bill of materials).

Hey Eyekon,

Welcome!

If you want it bad enough, why not just buy one on ebay? As of this writing, there is one for sale by a Canadian seller who will likely ship to your location.

Hey Drench, "...you could...put a bike grip on the grip" - I do have a rubber bicycle grip modeled in the screenshots that is over the CPVC. It's not very apparent because I didn't model in any texture on the grip. Above the gold brake lever clamp is the black external 25-degree spacer. If you zoom ...

Re: Next generation rubber CPS homemade water gun planning

Drench- “...I prefer a real pistol grip...” - I agree that a real pistol grip would be slicker. Are you suggesting just a pistol grip or a pistol grip with trigger? I don’t think I could use a pistol trigger unless I were using an electric or pneumatically-actuated valve (very short travel). If I us...

Re: Next generation rubber CPS homemade water gun planning

Hey Ben, "I think a 4.25 inch ID tube is way too big." - The large OD allows me to put the valve inside the PC cover. Maybe I'll just build up the bladder to a larger OD. I'm thinking I might try to use Gum Rubber Tubing (GRT) instead of LRT. Sling shot enthusiasts use LRT and GRT interchangeably. T...

Re: Next generation rubber CPS homemade water gun planning

<bump> I think Ben is really on to something here. I was hoping there would be more interest in this thread. No worries, I will design what I think is best, and I can tweak the final design before building in January. I will go with the 4-1/4" ID (4-1/2" OD) polycarbonate PC cover. This will allow m...

Re: Backpack soaker

Hey Dino,

It depends how extreme you want to get. Operating the POPCAP is fun, but a setup with an LRT bladder (homemade or store bought) and a hydration system or solar shower backpack reservoir will be easier on the wallet.

Re: Cps 1000 issue

I cannot elaborate because I am on a quick lunch break, but perhaps this thread can help. It suggests putting a rubber band around the valve pin. Below is an example of a valve repaired with a rubber band. Your valve looks different than this one, but it's still a good visual. http://www.blisstonia....

Re: POPCAP

Hey Drench, SuperCAP was a proof-of-concept for CAP. My initial intention for POPCAP was to be a proof-of-concept for a new trigger system (which ended up being the POP). The POP evolved from research and planning; the laminator evolved from trial and error. I wanted to showcase new nozzles, but the...

Ben- It sounds like you have something different in mind, but you reminded me of the “other” Uber Soaker ? This particular design required no modification to the cylinder. They made a custom housing that bolted to the cylinder. The movement of the cylinder rod within the housing displaced liquid thr...

Re: Next generation rubber CPS homemade water gun planning

All, As Ben pointed out, polycarbonate would make a better PC cover than acrylic. McMaster sells economical polycarbonate tube for flow in 3" ID (3-1/4" OD), 3-1/4" ID (3-1/2" OD), 3-3/4" ID (4" OD), and 5-3/4" ID (6" OD). They also sell less economical polycarbonate tube for fabrication in 4-1/4" I...

Re: Next generation rubber CPS homemade water gun planning

"Does anyone have any other ideas for materials for a reservoir?" - I have several ideas, I just need to know what capacity is appropriate. You mentioned 3 liters & 4 liters. What do others think? SEAL, marauder, DX, anyone else?

Re: Next generation rubber CPS homemade water gun planning

Ben– Come on, Ben! Give the people what they want: an onboard reservoir! In all seriousness, you should build what you prefer. There will be enough complications trying to improve the core CPH design. A reservoir would be great to consider for a subsequent version. I want my next build to have an on...

Hey SEAL, I agree; it looks like it was somewhere in that range, but hard to tell without solid proof. I was not looking at the stream directly. I had my eyes on my phone to try to get the stream in the video. It was a bit awkward shooting the video with my left hand while shooting the soaker with m...
