Andrew, my messiness can overcome any structure! I need to practice discipline in putting things away after I use them!
Always seems to happen that I get called in to dinner, or off to a meeting after working outside, so I grab all the tools and pile them on the bench. I gotta start planning on finishing and cleaning up, BEFORE the end of the day,or some other deadline. Hard to do for me -- I always want to do twice as much as will fit in any particular hour.
DMIOM, I actually do have one -- and great idea! But different dimensions since this space is so narrow, and unfortunately, different size drawers. But good one!
BackofEnv, Great I hope something here is useful! This bench is pretty much designed by Dave Gingery, with some changes for dimensions and the top material and divider thickness.
Today, I added the dividers, and scooched the bench out again to fasten them in place to the backboard.
A strip of 1x 4 was added to the top and bottom on the front side of the bench to fasten the dividers there as well.
I cut a piece of scrap plywood as a spacer gauge while screwing the dividers in place, you can see it in the pic below. It's exactly the desired divider spacing (greater than the actual drawer size), and I slid it in, top and bottom, front and back while fastening each section. If it slides and fits everywhere, that's perfect. And it does. A lot easier than measuring and marking, and keeping things aligned by hand.
