    Hi guys im 13 years old and im into guns and i am making a 80 PSI airgun starting form a pvc air tank brass fattings conecting to a ball valve or brass conector compressor gun thingy as the barrel will be a 1/2 inch copper pipe 45 cm it will shoot small objects or small darts i will just use for shooting potatos and size nails

    Got all the parts, looks very very interesting. I wander about the pressure in the tank and the mouth velocity."industrial one" -:) Very good idea indeed to show that, in fact, behind all the Montecarlo wood and other fancy stuff ont PCP s is producing power....almost schematic..like it...

    are they really sights? i cant see what you actually put on the gun, if it offers some magnification, its called a scope instead of merely sights

    I've had some experience with coke bottle air chambers and all I can say is that it is not a good idea. I have the scars on my hand to prove it :) Ask receiver545 (Another Instructabler) if he thinks it's a good idea, he has scars too.

    The safe pressure for coke bottles is about 80 psi, which is not very high, which means low power.

    Also coke bottle are not meant to withold constant change in pressure. This weakens the plastic, long story cut short, one day say byebye to your hearing, fingers or eyes.

    And the moral of the story it coke bottles are good for holding coke not pressurized air. 

    A word of wisdom, Always do your research when making something potentialy lethal. Remember homemade guns can be more dangerous then the real thing, because the real thing will most likely not explode in your hands. :)

    Awesome, I lived in Centurion, Pretoria before my parents moved to New Zealand(I was two years old).

    80 psi = 5.51580583 bar

    P.S. Your english is fine.

    Also coke bottles will most often be able to be pumped up a bunch of times before they pop.
