WELL, if you are having trouble locating Stainless Steel for your electro tank, the first place I would look is my local junkyard, scrap dealer, recycling center, one of them places. I had a WAGS member, said he looked high and low, and looked everywhere, and could not find any Stainless Steel for his electro.
Well, I found it, one phone call, that was it, they asked me how much I needed, they said they usually had a ton or two at all times laying around somewhere. SO, I went there and got some nice size sheets, that would/will fit down into a 55 gallon barrell, cost me almost 12.00 for damn near what seemed like a trunk full.
I got about 12 pieces, lets see, I have the same two pieces I started with, and they have lasted over five years, so I got two dollars in them pieces, and so that means that my Stainless Steel for my electro is costing me forty cents per year.
Now I figure if I use these a couple more years I can get that forty cents per year down into the 35 cents per year range. I ain't too good at math, so if somebody wants to rework them numbers, knock yourself out. ;)
