Shellacked and waxed, loaded with tools, sufficient room for more; I’m calling it done.
The lower drawer ~could~ be labeled “Heads,” with the upper drawer being labeled “Tails” (and assorted mandrels). The top holds face plates, frequently used wrenches, and that plastic bottle is full of jigsaw blades.
One of the photos explains why I wanted non-protruding drawer handles. That storage position saves room in a small shop, and for the curious, does not get in the way of using the treadle.
