thanks for you help, maybe ill be able to make a pop can launcher with this

I was wondering if this tank would be safe to use: http://www.balloontime.com/display.php? ... _largetank

it says not to refill it, but i dont see why i couldnt. i was also wondering if any of you know how much pressure this could hold.

i have been thinking about using one in a mini coaxial as the piston that seals the barrel, that way you dont lose any air to a pilot chamber

do you have a diagram of how it works? i cant find one on google

title says it all

is there something wrong with my sprinkler valve?:
(note the sound while i am filling it)

ive decided to use this instead for my ignition. it is the circuitry out of an old flatbed scanners external light thingy (i think the light was florescent).

this is what i would do 1. clamp a piece of wood or cork to the drill press 2. drill 1/8 hole 3. remove 1/8 drill bit 4. put in copper pipe bit/cutter thing 5. cut out cork 6. take out copper pipe bit/cutter thing 7. remove cork circle 8. glue 1/8 bit in cork 9. glue cork/bit into pipe 10. epoxy it ...

have you looked at valves sdk? i use their map editor hammer as a cad program all the time, it is really easy to learn and use.

all i know is that he did not get it online, but i have seen some signs like the one i took this from online

i would buy a stungun if i could but i doubt i could buy one at the age of 16...

actually this one runs off of a 12v transformer
so i could probably hook it up to a battery

i am planing on making my first combustion so i was looking at the sticky in the forum about ignition sources and when i scrolled down to the neon sign transformer i realized i had my ignition source =D

if i had a better compressor i would, but the one we currently have only goes up to 135, and i have an electric bike pump that goes to 120 and is alot smaller so i usually use that.
