Routing Dados with Shims

Routing dados and grooves across boards typically involves making two passes with a straight router bit while guiding the router against a straightedge. The problem is that resetting the guide for the second cut is time-consuming and leads to errors in the width of the cut. A quicker and more accurate approach is to make the second cut by placing a shim of the proper thickness against the body of a T-square clamped against the work-piece, as shown at right.

Cold Glue-ups Feel the Heat

In the winter, my shop can get too cold for glue to cure properly. Under those circumstances, I enclose my assembled project in a "warm box" made from 1/2"-thick, foil-faced rigid insulation. The interior of the box is heated using lamps or a portable electric heater. When not in use, I stash the flat panels away with my plywood sheets.

Available at most home supply stores, these 4' x 8' foil-faced sheets of lightweight foam insulation can be made into a box of almost any size simply by cutting the pieces with a utility knife and then taping them together. To create the walls for small- or medium-sized boxes, you can score one face of a sheet, then snap it toward you from the unscored side to create a folding hinge at a corner. Leave one corner of the box unattached to create an access door. For the roof of the box, just lay a piece of insulation on top of the walls.

Hang a cheap thermostat inside the box to monitor the temperature. A thermostatically controlled portable heater can be used to maintain the interior temperature at about 70°. For heat, you can use a high-
