how do i connect a soda bottle to pvc or copper pipe? Answered

i am making a pneumatic rifle with a soda bottle...i just have no idea how to connect the threaded end to further piping such as valves and barrels. any help?


DUCT TAPE!!!!!!! or do wut orksecurity says..........

yeah definately do wut he said

Drill a hole in the cap, epoxy the cap to the pipe, thread the bottle onto the cap and hope the threads will hold pressure well enough?

Or just epoxy the bottle right to the pipe? (That'll be a pain if the bottle ever bursts, but I suppose you can just cut it off and epoxy on another.)

Not sure how much pressure a soda bottle will hold, though.
