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?

Welcome back.

You should be able to pick these up at your local AutoZone or order online.

“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...

US military "water guns" are nothing new...

:-P

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 ...

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...

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 ...

Hi Andrew,

I cannot quantify the level of smoothness, but below is a link to an image showing something printed in this plastic. It would be polished by Shapeways just like the item on the right in the image.

Hi Ben,

I do not need a material to co-print the nozzle with. I am just looking for suggestions for lubricants or other coatings that I can rub or slather on the inside. Just curious what might be best suited for what I am trying to accomplish (vasoline, food grade silicone, wax, etc).

Thanks,

Tim

If I were to 3D print a nozzle for a home made blaster using Shapeways' "Polished Strong & Flexible Plastic" (Nylon), what would be an ideal NON-PERMANENT coating to reduce friction inside the nozzle? Assume that the nozzle in question attaches and detaches easily. Shapeways' Polished Strong & Flexi...
