Re: Coating to Reduce Friction Inside 3D Printed Nozzle

<insert yet another double post here> I am finally happy with my flow straightener and nozzle setup. Of course it started raining as soon as I decided to measure and record video. Below is the only video I have so far. The tape measure in the video is strung out 80 feet. Unfortunately, in the time i...

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 ...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

Hey marauder, I do have some pictures, but I am refraining from posting images until it's complete. Once I post a guide, I don't want to keep having to update the photos and bill of materials. The blaster has been functional since last Monday, and yesterday I completed the trigger system. Now, I jus...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

<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...

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

Ben – Perhaps you could initiate a Kickstarter campaign at some point? Even with a run as low as 99, an item like a Catalina low pressure cylinder can drop in price by over 75%!

HBWW – What direction was isoaker hoping for?

Hey Ben,

When was the last time you made contact with Buzz Bee Toys?

Are they lurking silently around these forums?

What do you think is or should be the next frontier for them?

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

“Stepped Contraction” - I’ve coined my first phrase! Sweet! I agree; the value of the contraction is understated, and perhaps the value of a tangential injection is overstated. However, we must admit that the tangential injection is not a detriment, especially because it is followed by a large diame...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

The effect of a stepped contraction is an interesting thought. This is inherent to certain homemade soaker designs as you pointed out. I suppose an inline stepped contraction would not lend itself as well to soakers based on SuperCAP, UberSoaker, Dusty’s Water Gun, etc. However, these designs (even ...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

Hey Ben, Thanks for sharing; that chart is interesting. Are you suggesting I use a 2.5" ID pipe to supply a 1/4" nozzle outlet? That doesn't sound very practical for a water blaster. It would waste much water after each trigger squeeze assuming the supply pipe/barrel is after the valve. The Theobald...

Re: Coating to Reduce Friction Inside 3D Printed Nozzle

Very good points. As you indicated, a coating may be critical or pointless. How can I best design the nozzle to mitigate the effects of my anticipated roughness to reduce the potential need for a coating? Would it be beneficial to make the nozzle as short as possible? In other words, would a sudden ...
