Laserstream in Rosebank Rd (still ?). They do water jet cutting.
Set-up cost and then piecework after that

A problem I see with anything like a laser or water jet is that it's
going to go through the one side and then what ? It will still have
enough energy to do something interesting to the other side. And
you'll have a can full of water, sand or laser

You need one of those whips like what Vanko had in Iron Man 2

I've a very very fine oxy-acetylene torch which the very skilled
can work aluminium cans with. Don't know how you'd get on
with a plasma cutter
