When I say tool organizer, I mean that it allows me to place the tools in ithang them from it. It does not actually help me prvent the loss of drills or bits or any other tools places on or near it. Well, actually, it is qhat it commonly referred to as an organizer, so...
When I say scrap, I mean pieces of wood, leftovers and stuff you would not usually use except for such purposes. There you go, I think that sentence was just a fancy way of saying nothing you did not know already. Anyway, moving on...
Step 1: Materials and tools
board(s) - I used a piece of leftover for the back and pieces that came with the packaging of some furniture (called particle board I think, and with fake wood surface, as well as parts of slats from an old bed frame)
Step 2: Figuring out what goes where
There are, of course, several ways of storing tools, and far more than I can ever think of are described here on this site. What I did could easily be improves upon, and I do not expect the design to be finished - either it will fall apart because particle board does not lend itself to being screwes that well, or because I find new ways of adding clutter.
