Okay, I tried the wire rack ideas mentioned here and I'm dumbfounded how easy this was. I hit up the local Dollar Tree place and got a pair of stepped wire shelf racks. They provide three levels of stepped storage for spices or similar and are about 12" wide and coated in white vinyl.
A quick trip through the metal band saw shortened the assembly to a "W' shape that worked out really well. Flip them upside down and put into the toolbox drawer and- wow. It worked great. Pliers slipped right in, stayed vertical, no problem. I regained easily 60% of the storage space in that drawer alone, and the pliers aren't piled on top of each other. Now they are easily accessible.
I had a leftover piece that was one set of wire tines still attached to one set of the taller legs from the back of the shelf that sort of resembled a rake or comb. I looked at that and realized it sort of looked like a pegboard hanger for screwdrivers or similar. I bent the long legs to the offset for pegboards and bent each metal tine about 1/2" in from the tip and up at at about a 45 degree angle. Test fit and- tada! Instant shelf for pegboards, or storage for screwdrivers orwhatever you want. Pretty darn nifty.
Total waste was two 1.5" pieces of wire and four vinyl wire caps that I kept for future projects. That's really affordable at $1 for each 12" rack!
And I'd have never even have thought to even know about storage options like this if I hadn't stumbled across it here on GJ.
Thanks guys. That's really cool.
