I heard there was something bad about coaxials...hmmm, i just want whatever will be most accurate with a velocity around 450fps, is there anyway to use a program to determine speed of projecti...

Bolt Action Rifle run on Propane

Hey everyone, I have made a pretty successful C02 bazooka that runs on propane, with a leveled out bottle of gas it takes about 2 minutes to get to 45psi and then fires nerf vortexes like a champ. I want to try something new now, but im not very good with the tolerances of pressures, how to create p...

BBMG operating pressure?

I want to make a 3/4in cap bbmg. I want to run it with propane that expands in a 4inch 3 ft tank. Id be firing at around 60 psi at max, and 90 if i let it sit for a LONG time. Is 50-60 enough to fire bbs with substantial force? I will have a 450 mm barrel.

Push Button Valve?!

Can I use a push button valve as a pilot for a sprinkler valve?

Would it operate well, and with ease?

haha, 37 is a bit pricey for my taste. I tried a different trigger valve and still no luck! my pvc goes from a 2 inch chamber to a 1inch sprinkler valve, is that causing problems? The finger still works, dunno why trigger valves wont. Is there such thing as a super high flow blowgun? Im all out of i...
