The shelf on the desk

This is all about the shelves I built about 4 months ago. Probably should have taken a picture before I filled up the shelves, but here it is in use. 

Again, all the wood I used was rescued from burn pile at the local dump. Most is 3/4" plywood. The outer frame and middle separator are 5 1/2" deep (the actual width of the 1 x 6 plank on the left-hand side) and held together with screws. I intentionally left enough room for my home-made cardboard spray booth to fit under. The three inner shelves on the right are 3 1/2" deep and are held in place with doweling and glue. The two inner shelves on the left are around 3" deep, maybe a bit more, and have a backing behind them (the rest of the shelves are open-backed). The tool holder on the bottom left is a 3/8" plywood and roughly 4" wide, installed at an angle with a parallel piece behind it to act as a stop for the ends of the tools so they don't end up behind the desk. Also left a bit of space under it to put things like small pliers, side cutters, rulers, etc. The unit is attached to the desk with some L-brackets left over from a different project. It's been very nice to have.

Looking at the picture, I can see at least 5 unfinished works in progress. Some of which have been in stasis for 5 and 6 months. That's how distracted I can be, though I'm hoping to work on things to be quicker at finishing.
