Shelf Pin Jig free project
I like drilling shelf pin holes in the top, bottom, and both sides of a box so that it can be used vertically or horizontally. But that means aligning and spacing of all those holes becomes fairly critical. After all, you do not want crooked or wobbly shelves. Nothing works better for uniform spacing than a layout jig.
