I got tired of looking for the perfect fit. So one day I took every Socket, Extension and Wrench I owned and measured them up and designed Socket Trays and Wrench Racks for an exact fit.
It was quite the process but one I had everything loaded in Cad the unfolding and programming was easy. Loaded the programs in the Laser and cut the 16 ga Stainless, ran them through the Timesaver to put a nice grain on them and off to the Press Brake. Formed them up, welded where required. All the Wrenches, Sockets and Extensions dropped right into place.
The only catch is they are very set specific and overtime I found Craftsman changes thickness of Wrench handles and Socket diameters causing a few issues if I have to replace a tool.
This is a picture of my "small" set I got when I was 16 years old from my Mom for my birthday...I have added a few pieces to it over the last 36 years.
Here is my Master Set, 7 drawers full of Wrenches and 2 Drawers of Sockets. Someday I plan on doing my Ratchets and Screw Drivers. In a glance I can see if anything is missing.
