The Worlds Most Expensive Shelves-assembly and finish!

So, the very first thing was to clean the years of
accumulated crud plus smoke residue off of the
shelves. They were REALLY dirty!

Then we set up the workmates, boxes of hardware, tools and uprights. I put the feet on the uprights as soon as the paint was dry. I had a square handy, but there was surprisingly little tendency to become a parallelogram. Eight screws, nuts, and lock washers on each shelf. I had flat washers, but there wasn't room to put them on.

The finished product! I have three 5 shelf units and one 2 shelf unit. Very sturdy!
Total cost; maybe $100 in materials and five years agonizing over the process.
