Just a note- While fitting the pieces to the cage, I found there were some unexpected hazards. I believe to always fit first, disassemble, finish and THEN assemble. The nest for the kitchen was sitting on my table saw (finished and ready to install). For some reason I was looking at it thinking that there was NO way that the box could fit in the opening of the cage. I took a tape to the box and found that I had made a BAD change to the measurements in error when I went from 1/2" to 3/4" stock. The box was over and inch too tall. I was SO mad that I let it sit for a few weeks before I completely cut the top back off and fit it back to the box correctly. Then the reseal, paint and lacquer. (What a PAIN). NEXT-just before I was sending the cage to powder, I fit the black strong box to the inside. I have to lift the cage as the larger pieces will only fit through the large opening in the bottom. I found that I would not be able to get the box in unless I removed an upper shelf bar, and weld it back in when it got back from powder... not an option. I decided to mount the box, re-weld the bar and shoot the cage in the driveway. I had some old white Polyurethane from a car project. Could never wait to get the temperature right, so it ran like a hot candle. BUT, at the end of the day, I got it smooth AND it will be mostly hidden in sheet metal skin. Since then- I added the kitchen nest (box) and got to the shop to sheer the gray sheets to start adding them on this weekend, and everything is good.
To sum it up- Life's Short. Don't get too frustrated with builds. Just remember the end-game and big picture....The problems are just a small drop in the bucket of a happy life.
Cheers
