I'm a mechanic by trade, and found that with all the comercial socket rails, they take up too much room and are quite often a pain to use. I solved this by taking a scrap sheet of 5/8" plywood, placing all my sockets on it and used a pencil to mark where I wanted them to be ... Ie: from from to rear, 1/4" then 3/8" then 1/2" shallow, then repeated for deep sockets. Aster I had them layed out, I drilled the appropriate holes to accommodate dowel that I tapped into the holes. I did not still all the way through, and did not glue the dowel incase I wanted to change the dowel out if it got oil soaked and swollen. The dowel was cut off to extend about 1/2" above the board, and I used a sander to put a chamfer on the top of the dowel to make dropping the socket on easier. The result is a socket board that holds all my sockets, takes up half the room that the commercial rails did, and the sockets take zero effort to remove and drop on, but even the tallest of sockets will not tip even if you shake the drawer!
