****! and that was just an angle grinder spark rather than a welding arc

A spark is a spark is a spark! Even static electrickery can cause explosions under the right conditions. Did you never explode ordinary baking flour in a tin with static during school science lessons?

Just read the story, thinners or anything solvent based(easily becomes vapor) is a proper no no just like petrol.
A couple of units down from me someone nearly died cutting a 45g drum that had fibre glass resin stuff in it.

Its what is known as "natural selection". I've cut more than a few gas cylinders open for wood burners, chimeneas, and bbqs etc. but not before making sure they are completely empty.

I use the positive displacement method of venting any remaining gas, unscrewing the valve, and filling it with water. If its full of water then by default it cant have any vapour left to go bang. Drain it out and cut away.

My latest project a hot smoker (no pun intended). Would be a lot easier to cut the compound curves with one of them fancy plasma cutters but my old lady wont let me have one so grinding discs it is.

As in all things I'm not encouraging anyone to do this but if you do its entirely at your own risk.

Neat work there Shifty

Thanks. The hardest part is marking the curves as its easy to bollix it up leaving a shed load of grinding and adjustments to get things to fit. Ultra thin 0.8mm cutting discs make it reasonably easy to follow the curve so long as you take your time. The steel in the cylinders is relatively soft and about 3mm thick so once its all welded together it should last a few years and there's nothing like beef brisket or a leg of lamb thats been slow cooked for 5 or 6 hours over a wood fire. Makes it worth the effort unless you're a veggie.
