i an going to try to tap the neck of the bottle with steal have a 1/2 1 inch long steel nipple then i'll try to convert to pvc, steel doesn't really fit my budget.

I have 3 of these, and they SHOULD hold up to a good amount of pressure, but don't take my word for it without testing.

Oh and BTW these bottles are a few years old.

Pc guy i dont understand you have 3 of the bottle or guns with those bottles?

it's my birth day today also so hello new funds.

[PCGUY]

3 of the bottles, I've never seen a cannon made from them.

Here are a few guns posted on the Spudtech forums that use the aluminum bottles.

So no one has ever pressure tested one?

[boilingleadbath]

None of <i>us</i> has pressure tested one... but I'm absolutely certain that the engineers that designed the things did extensive testing, because stuff like "designed beer bottle that cost bud wiser millions in lost inventory" looks <b>really bad</b> on your resume.

That said, I'm going to have to say that epoxying the neck into a matching taper is your best bet.
Perhaps you could use a forming method similar to that used to make the flares on PVC rockets to form this taper.

Will pipedope work for a steel fitting going into aluminum?

spud blaster- the cans arent really paper thin but i can see your point.
