Re: Interesting firing valve used in air cannon, might be worth investigating

I already made the valve used in this in a water gun. If you are using it to make a single shot gun then it's great. But for a rapid fire design it's too slow to reset the valve ie every trigger pull however slight fires it all the built up pressure at once.

Re: Accumulator tanks as pressure chambers

When I get back to Oahu I will run some tests but I believe that the largest one (the gallon tank one) went 65 feet at 115 psi which isn't great. The key limiting factor was the nozzle's inefficient focusing of the water. I think the sweet spot will be somewhere around 1-2 liters in terms of outer t...

Rather than getting one of these you can just easily build your own. I built one two years ago more along the lines of a ZX-2000. http://gemmy.wikia.com/wiki/ZX_2...

Re: Accumulator tanks as pressure chambers

http://i167.photobucket.com/albums/u151/cdmttib/20170423_1735331.jpg Here is a slightly different iteration with a single chamber. I am going to be playing around with the chamber pre-charge. I think that I want to have it at around 50psi. The next thing I want to do is make an outer frame to hold ...

Re: Accumulator tanks as pressure chambers

Sorry it took so long to reply it's been very busy for me lately. As to your questions amazingly the Chinese toy squirt gun wasn't glued much like the smaller stream machine where you can remove the forward nozzle. It's thread pattern roughly matched to garden hose fittings. All I needed was a littl...

Re: Looking for water gun from the 90s....

No that is the right type of gun. It shot regular water and using hydrodynamics the ball that shot out was a ball of water. It was shot with one pull. They had a few models you probably just had the other one not picturedlanet Wild Planet Waterball ML 100-Sports Launcher is another one but Ibelieve ...

Re: Colossus 2 CPS Conversion

Marauder another option you might consider is to make a hydropower version by modifying something similar to a Shurflo Accumulator tank and making some precise scalpel cuts in the colossus 2 frame to accommodate the vertically oriented frame of the tank. Or you could snake out a tube from the water ...

Re: Isoaker 2015 range testing

Great work CDMT. This data is very valuable to me. Thanks for including the chamber length as well. That made me realize I forgot something which I might be able to calculate from the chamber length. Is the chamber length how far the piston moves? If so, then I can calculate the water volume. If yo...

Chinese Oozinator ripoff minus goo

http://www.amazon.com/gp/aw/d/B00KFLAT14?psc=1

Never ceases to amaze me how often the Chinese ripoff products. It looks like they reused the old molds and removed the bottom section where the goo was held. More than likely the internals have been completely replaced with worthless rust prone junk.
