: hmm, well, question 1: : is the 3/4" elect. sprinkler valve worth dealing with? : is it better to go 1" ? eventhough internals are the same? BT: The only advantage I can see is the cheaper connections for the 3/4". A disadvantage of the 1" is that extra "deadspace" after the valve that must be pressurised to push out the round. But that's a very, very small detail. : is there such a thing as a psi-actuated switch that can complete a circuit? (i guess it would be called a pressure switch?) like, once the pressure agaunst the switch reaches a certain point, it completes the circuit? but not pushbutton, i mean accurate to a certain psi.... BT: What a concept! Pressurise the air chamber and when it reaches the set pressure, the cannon fires. Never any air in the air chamber unless you are firing. Might be safer. But would definitely be a delayed shot. I think out loud too much. Moving on. : and the last one... can i ask how l.e.d.'s work, or should i just go to howstuffworks.com? i think ill go there anyway, but its nice to get stuff in english. i went through a class on diodes in the army a couple months ago, but the instructor glazed over leds. also, how do they not act as a short in the circuit? seems as though theyd steal most of the current, as their resistance is generally less than that of the connection that they display is present ( i just had a thought... are they inline with the main wire? i for some reason assumed a parallel circuit). anyway, um, i guess thats it for now... BT: Like Dale said. Extremely small current drain. : oh, also, what width of plywood do you use for sides, and also what do you use for.. and how thick is your framing (goes to all ppl, id like to get lots of answers to these 3 esp!!) BT: Depends on the application. 1/8" would stop a paintball. Framing - whatever it takes to hold the shape. HellFire is 3/4" or 1" steel tubing. Used to be 2"x2" wood. : anyway, thanks for your time, hopefully see some guys onthe field sooner than 6 years, lol Oh. So you'll be a little busy for 6 years? Drop by when you can, we'll have a ball or two for you! Do you prefer 21 paintball cannons or Tippmann Flatlines at 20'? ;-) Bill Tison HellFire
