I had the occasion to try building some drawers using Mark's pocket screw method yesterday. It works extreamly well, even better than it sounded when he explained it. I made 6 large drawers, 23"DX35"HX10"H. The only thing I did differently, or actually added to, was to make a 90 degree jig to hold the pieces in place while I drove the screws. I'm probally an intermediate to advanced woodworker and I've never made drawers that turned out as square as these. I like this place.
