The more I look for scrap metal in my area the more I realize I live in a junkers wasteland where nothing can be found for cheap. I have a half-dozen long blades I need to quench after forging that are too long for my stainless stock pot. After this handful of long knives are done, I will no longer need the taller tank. This tank will be used outside, away from the shop with proper adult supervision and extinguisher in hand. If I had a permanent need, I’d pay the roughly $100 for a metal pipe to be shipped. So, my solution is a piece of pvc pipe (I know), with a heavy stove pipe insert so the blades will not come in contact with the pvc. okay for very careful, temp service, or fuggitabout it?
