Is there a low cost alternative to a commercial Brownells bluing tank? I need a metal tank for boiling water only. I was hoping to be able to find something like a metal wallpaper tray, etc.
I find there are often things in other industries that we can utilize (like automotive, etc.), but I can't seem to come up with anything.
Basically I need a 30 or 36 inch tank, say 5x5 or 6x6. Any ideas?
