Papaw and fellow froumers: I stumbled into a junk storage building last week that would have blown your minds. I too, thoughtabot the old library card storage gig for tools or nuts and bolts etc. I found the holy grail for access to them. This ol' boy has a couple dozen of them(72 drawers per unit). The stubling block is the price. He's asking $320 each for them. These dabies haven't seen the light of day in years. If only I were rich.....
BTW, my solution for storing wrenches with holes in the handles is solved by this eyewear optical board I bought for $5 . It is mega heavy duty and each peg is a bolt actually and would easily hold 100# each(wall might not survive the total weight though...lol)
I think I posted a photo of it, but if not, I'll try to dig it up. The board looks like Swiss cheese with all the options of where to install the hangars.The board is about 49" tall, 24" wide, and the pegs stick out almost 4" and there must be like 40 of them to move around as syou see fit.. I wish the gal had more of them, as at $5, it was a steal.
