Scale it up or down, knock it down freestanding bookshelf.
Four square holes near the corners of each shelf make this bookcase easy to build and adjust. The knock-down system, designed by architect Henry Wood of Mountain View, California, could be scaled up or down to suit your needs.
Each 12 1/2- by 31-inch shelf starts with an 11- by 29 1/2-inch piece of 1/2-inch plywood (birch or A-grade fir). Cut a 1 5/8-inch square from each corner to accept the finished 2 by 2's that are the uprights. Then trim all four edges with mitered 1 by 2's which extend past the cutouts to create the square holes.
All four 7-foot 2 by 2's have 1/2-inch-deep, 1/2-inch-diameter holes spaced 6 inches apart down one side. These holes receive 1-inch-long, 1/2-inch-diameter dowel pegs that support the corners of each shelf. At top and bottom of each pair of uprights are 8-inch-long spacers, joined to the uprights with 1/4- by 2 1/2-inch lag screws.
To assemble, screw the legs (with peg holes facing one another) to bottom spacers. Add dowels and shelves, a row at a time. Finish with top spacers.
Top and bottom shelves are securely anchored to the uprights with countersunk 1/4- by 2-inch lag screws. Screws through the back lip of the top shelf anchor it to the wall studs.
