snd PS in pneumatics the pressure of the air condenses Dihydrogen Monoxide vapour out of the air and so they are dangerous too.

OMG! :shock: :shock: :shock: My gun is more deadly due to DHMO than it is due to projectiles traveling at 600 feet per second! :shock: :shock: :shock:

Just kidding.

If my IQ was only two digits, I might have fallen for that! That would be a good joke to pull! I'm going to try it on all of the environmentalist hippies at school!

And where is your proof of that? 600fps is a pretty big claim, and i cant seem to find a link to your gun, have you posted it?

I used the GGDT to estimate the speed (No chronograph for me... :( ). The results might have been skewed somehow, but I was conservative on the gun parameters, such as pilot volume and seat diameter, (It's an un-modified solenoid valve), so I think it's reasonably accurate. If I discover how to upload stuff to the internet due to me being a computer ignoramus, I'd be more than happy to post the gun. If you'd like to test it yourself, it's the same design as the PSR-01 on PVC Ballistics. Is 600fps really fast for a spudgun? I don't really know what a reasonable speed would be, as I haven't built many spudguns. If my estimate was wrong, oh well, I suck! :D

600fps for an un-modified sprinkler valve pneumatic isn't gonna happen, even for a modded valve that is pretty damn fast.

Oh well... :oops: I know it's much faster than a paintball, though, by at least 100 fps. Would 400 to 550 be reasonable? HOLY CRAP I want a chronograph! Then I'll know for sure! Does anyone have the parameters for a 1 inch inline solenoid for the GGDT? I tried to find them, but I couldn't. Thanks in advance!

The parameters for an unmodded sprinkler valve are on D_Halls site. :wink:

Thanks!! Does the brand of valve have any significant impact on performance, such as guide rods weighing down the diaphragm or something? My valve is Nelson.
