[TheForge] old propane tanks

[Ron Childers]

Actually, the stuff in acetylene tanks is porous and he just chopped it out and made a pretty nice bell out of it. Most bells I've seen with a flare at the bottom look rather lumpy; I'm thinking of a jig to get a nice round flair. Maybe a "U" shaped 1" round bar and a rounding hammer? Has anyone tried flaring a tank?

We regularly repair aluminum diesel fuel tanks and aluminum hydraulic
tanks at work. We usually wash them out with water then fill them with
argon or C-25 (75% argon / 25% co-2) . That displaces any burnable
fumes and any oxygen. I would do the same if I was going to cut a
propane tank.
On the other hand you could (perhaps) crush and sell the propane tanks
to the scrap yard then use that money to buy some less dangerous tanks
like used freon tanks.
