tower work

I've been working hard on getting the tank ready to haul back to the foundation...welding in floor joists, laying in floors, cutting in and framing out windows.

Here's the floor joists. 2 1/2" pipe on 2' centers.

I had a bunch of salvaged 2 x 10's to use for the floors. It took quite bit of head-scratchin' to figure out how to get all the floor boards cut to the correct curvature of the tank. Each board hits the tank wall at a different place, creating a wide variety of chords. I couldn't cut them too big and bring them in to size as they wouldn't fit in the tank and, if they were too small, well, then they're too small! It worked out pretty well, though.

The windows were also very tricky. Not only was it difficult to cut out the hole correctly using a cutting torch on 1/4" steel, but the curves made it hard to get the size right and the windows I am using--scavenged from somewhere so long ago I don;t even remember where I got them--are a bizarre trapezoid shape. I'll make the windows operable as I'm pretty sure the tower will be hot inside if I can't ventilate it with open windows.
