Re: POPCAP

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: POPCAP

All, I updated the guide to include official ranges, a revised discussion of the nozzles, and more videos. Ben, "...the expansion from 3/4" to 1" increases turbulence..." - The valve is available with 3/4" NPT on both ends (Banjo Part # PV075), but the ID of the pinch valve is actually 5/8"; so, the...

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...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

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...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

Thank you for the encouragement, guys. Sanding the inlet of the 3D nozzles would not be too bad, but sanding the area near the outlet would be a pain. I'm getting bored messing around with the 3D printed nozzles. Perhaps I'll revisit this in the future and make one with GHT threads. For now, I will ...

<insert double post here> Ben suggested via email that I should test a drilled end cap for comparison to the 3D printed nozzle. I drilled a PVC end cap with a diameter that is within thousands of an inch of the printed nozzle's outlet. I could not convince anyone to go out in the rain with me to tes...

Re: Standardizing Hits

Just to mix up the conversation... Could you guys wear white T-shirts and use a different color food-coloring (or Rit Dye) each round? Bring multiple white shirts each so you can cycle through each color multiple times. If the color of that round exists on your shirt at all, you were hit. If you try...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

The 3/4" NPT nozzle is $20.24 including shipping if you choose Shapeways' extended manufacturing option. The 1" NPT nozzle is $27.33 including shipping with the extended manufacturing option. I was able to test the 1” NPT nozzle a bit, which has an outlet diameter of about 0.23”. I attached the nozz...

Re: APH Build - Aggressor MKIV Homemade Water cannon (Primary and Secondary Fire modes)

Kudos, Powersurge! I really like that piping layout. How has no one thought of this exact layout before? It just makes sense. This basic platform has much potential. Even a smaller secondary blaster could employ this layout if coupled with a mini pump like the ones that mount to a bike frame. VR, Tim

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

Reeling the conversation back to 3D printed nozzles… I had these Theobald nozzles printed with 3/4” and 1” NPT inlets. The initial diameters of the Theobald profiles match the ID’s of the 3/4” and 1” pipe nipples that I have. The nozzle ends have the external geometry of a 3/4” camlock fitting. I in...

Re: Nerf is "best-performing brand" at Hasbro

Ben , Plenty of people drop way more than $200 on airsoft guns & paintball markers. Why are we water folks so cheap? Is there any chance you could consult or collaborate with Buzz Bee Toys? They would get to sell a bunch of blasters, and you would get to pick up manufacturing experience (paid inter...
