I have an empty disposable welding gas canister than I'm thinking of cutting up for the metal. Does anyone know off hand what the thickness of the wall is likely to be?

Hmmm anyone else thinking that it's a really bad idea to cut into a gas cylinder... "empty" or not.

Naah, as long as its empty you will be fine. People do it on full size bottles, just remove the Tap fitting on the top and then cut away

Assuming we're talking about an inert gas it'll be fine. Not sure on wall thickness.

Why?

It's inert gas and as long as it has no pressure left I don't see a problem.

From a distant memory about 2.5mm btw.


ETA I must type quicker !

Co2 so inert gas. No risk of explosion here.

About 1.5mm

2mm for a Clarke disposable CO2 70mm diameter. Had one to hand as I chopped off a couple of slices in the past for something.
