OK, and now for a really silly question......

[Porschemaniac]

In my garage, I have several spent disposable Co2 canisters. When I say spent, I mean no gas and even the little brass valve floppig around!!!

These would be great for a little project that I have on, so I could really do with, ahem, 'modifying' a few of them (with a grinder).

Presumably, given that these are completely spent, they are now simply empty steel bottles? Before I do it, is there any good reason why I can't take a grinder to one?

I said it was a silly question (bordering on paranoid maybe) but it's always best to get a second opinion!!!

Cheers.

Co2 isnt flammable or explosive so there is no problem there. the trouble is they must and i do mean must be empty. if they have any pressure in them once you cut them you have explosive decompression. Full safety gear advised

Thanks Ironmaiden - exactly what I was thinking. Now, where's that grinder........

Would drilling a small hole first be a safer approach?

just unscrew the valve it's got hex flats on

Actually, I make both of you right and already cooked up a kind of hybrid appraoch; I drilled the centre out of the brass valve (couldn't get it to unscrew).

For anyone else, who may have this question, I can confirm - no worries - make sure the bottle is empty, drill the valve out to be sure and then cut to your heart's content.

Cheers guys.
