Why not build one yourself?

Re: New Linear Flow Valve

Hey Drench, I finally got around to assembling the valve. Although it may not be apparent in the video, this was quite a hack job. I had worse clearance issues than I anticipated, even with the thickness of the gate. To make the clearance adjustable, I had to cut the valve body in half and bolt the ...

Re: Life Straw

Hi marauder, That does look pretty cool. How would you use it to fill a water blaster? Would you have to suck the water into your mouth and spit it into the reservoir? Some similar products on Amazon have a little pump instead of using your mouth suction. Has refilling from natural water sources cau...

Re: Protection and Shielding

Hi Ben, Perhaps the lack of response stems from a lack of confidence that this would ever come to life? If you are able to make something rudamentary, I beleive this would generate much interest. You are a legend because of what you've done rather than what you've merely proposed. I guess my point i...

Re: MOAB 2016 (Official Thread)

Scott, I realize I am likely out of line interjecting here, but... This sounds very ungrateful to me. Why would you expect marauder to feed ~9 people on his dime? He didn't invite you to lunch; he invited you to an event. People traveled great distances to make it to marauder's house, but not all co...

Re: Accumulator tanks as pressure chambers

UPDATE: I contacted SPX Flow Technology in Sweden (owner of the Johnson Pump brand) regarding the connection on their 2L (half-gallon) accumulator tank . Cecilia Trumbäck informed me that “The metal connection going into the tee is 3/4” and BSP.” Since my last post, I found several other water accum...

Re: New Linear Flow Valve

Thank you for the encouragement, Drench. Below are some further clarifications in response to your comments. “1) The seals are minimal but also redundant.” Actually, only one of the four seals is redundant. Both of the larger seals are needed to prevent leakage through the top and bottom of the valv...

Re: New Linear Flow Valve

Hi Drench, Yes; that is my design. A few months ago, I said I'd be building a CPH in January (I should have said I’d start in January). As you may recall, the ball valve actuation mechanism I proposed was questionable, and to have any chance of working, I was planning on a 3/4” valve with a 5/8” por...

Re: Accumulator tanks as pressure chambers

Hi Ben, Nearly every racecar, plane, and heavy equipment tire is filled with nitrogen rather than regular air. There are several benefits of using nitrogen. However, for our purposes, the benefits are likely negligible. I was just thinking that if you have easy enough access to it, go with nitrogen....

Re: POPCAP

Hi Ben, Are you going to try to implement this "air sheath" idea in your next build? How will you construct such a nozzle? Would you employ a local machine shop? Do you think that exhaust from the pinch valve will provide a high enough volume of air for this feature? Are you thinking it might be eno...

Hey Ben, "A few people back at SSC made backpack blasters with accumulator tanks..." - I recall Dusty's Water Gun and Andrew's AR-1.1 "Typhoon" . Were there others?

Re: Source for water reservoirs

Hi Ben,

I agree; US Plastic has a good selection. I previously proposed a 4-Liter Reservoir sold by US Plastic. Are there any in particular on US Plastic's site that you are considering for a future build?

Thank you,

Hi Tyler,

As Ben pointed out to me in this thread, polycarbonate would be a better choice.

Re: My CPH just shot over 70 Ft!

Hey Tyler,

Yes; POPCAP's maximum water pressure is 70 PSI because that is the maximum pressure rating of the pinch valve tube interior.

Re: My CPH just shot over 70 Ft!

Can't wait to get that nozzle on my blaster! My forestry firefighting nozzles were such a bust.

Can you post images of your new laminator? Did you end up adding a third screen and a plenum like you mentioned? These features improved performance in my setup.

Hi Tyler, "Doesn't McMaster have a smooth bore 6" nozzle? Or I think I've seen them on firefighting supply places (usually $20-30!)." - I am strictly referring to 3/4" GHT Nozzles. The image on McMaster looks like the ones made by Moon American or Underhill - both of these are cast and have a rough ...

Thank you for the info, Tyler! These might just be the only non-cast, non-stepped 6" sweeper nozzles on the market. I've been looking for a long time. I've already placed an order at http://www.ewingirrigation.com. If you've already tried regular straws and shake straws, I'm guessing your 4mm straws...

Re: My CPH just shot over 70 Ft!

Hi Tyler, Once again, great work! Is that 6" nozzle as smooth on the inside as it is on the outside? Most 6" nozzles are cast (rather than machined from bar stock), so they are rough on the inside. Have you compared the performance of your 2" brass nozzle vs. 2" red plastic nozzle vs. 6" brass nozzl...
