A couple of stainless steel cooking pots. Big ones.
One or other of these is intended to be the tub part of a vapor phase cleaning system, for vacuum gear. Bought two because I haven't decided on the size yet. There's quite a bit more involved, so it's the start of a slow project.
They are probably too big for a vapor phase soldering system, given how much that fluid costs.
It took me ages to find these. Finally thought to try Sydney's Flemington markets on Sunday. Success!
Stall #830 There are even bigger ones, too big for my purpose.
Total paid: $125 cash.
20L $60 (was $65)
30L $65 (was $75)
Next size up is 60L I think.

No idea what the manufacturer's price is. But I figured that even if they're far cheaper to buy direct, arranging shipping on large, easily squashed things like these would be such a pain and expensive, that it was better to just live with the market seller's price.
They are seam TIG-welded, and the bottom seems to be thicker than the sides. Quite nicely done.
I think I can do the rest of the construction without altering or welding to the base pot at all. Fingers crossed.
The base heater will be outside the pot.
