we have railings at my work (wastewater treatment plant) that are made of two inch thick tube steel. I keep thinking this is excellent metal stand material...
For me, it began with bettas. I'd see a bowl or jar and think "I could heat and filter that." Then it grew. I thought about water coolers and cars as potential tanks. And then came the day I walked into my bank and just stood there wishing those panels were mine. I feel you on this one.
I was at the county courthouse filling some realestate papers looking at the doors into that section thinking the same thing. They were 1" tempered about 10 ft high and 3ft wide.sidewise what a tank.
that's what i'm saying. when i'm standing there in line, i can't stop thinking about how it would be to build a tank out of that stuff. it looks super strong, and clear.
