>I was thinking of two deeps deep and then i was going to make a little rack to hold bases and lids with a 1 - 2 inch gap between them - that was the plan anyway.
I found no need for any kind of rack for lids and bottoms. When I tried to do the unassembled pieces it didn't work because they stuck together so I just assembled them first, but if you wanted to do them unassembled, you'll need some sort of rack.
>But i like your idea of a third on the end in the middle - are you suggesting deep then deep on end then another deep length ways?
Not sure I follow. If you stack two deeps, just like you would on a hive and then put one on end inside you have what I'm describing. make it about four inches taller than that to give you some leeway when filling and the level going up and down as you add and remove and the boiling not boiling over.
>Sheet steel sounds great! cheaper is better Smiley i guess rust is only an issue where water is involved - wax, and the temperatures that it would work at, would negate that. I'd only need to make sure i put a heat paint on the outside of the tank to protect the outer surfaces
I think you'll dribble enough wax on the outsides that it's not an issue on the outside either. It doesn't take much to keep it from rusting.
I like the idea of bending it, but I usually don't have that nice of tools. I think I would weld it on the outside and then do a fillet on the inside. But I don't consider myself an expert welder. I thought I was an expert at a cutting torch until I watched someone cut a broken rusted pipe out of the threads on a pump and no damage the threads...
