Author Jeff Vollmer describes his boxes as key-and-slide—cut a dovetail key, cut a slider piece, cut another key, cut another slider. That’s the puzzle or “combination” you use to get to the chamber or heart of the box. Then you cut out the guts of the box to create a chamber. But wait, there’s more! Then you cut another box from the guts, then another box or drawer from those pieces, then another and maybe another until things get too small to handle safely. Any type of wood can be used to make these boxes, and flaws are just opportunities: holes, cracks, splits, insect and wormholes, spalting and burls. Puzzle Boxes includes a DVD that contains more than 90 minutes of step-by-step information. Puzzle Boxes will be available in February 2010.
