Thickness planers are worth their weight in gold, but adding one to your shop doesn't come cheap. If your budget won't allow for a planer just yet, we have a solution. Our surfacing jig turns a router into a serviceable planer. The moveable sled will fit virtually any make or model of fixed-base router, and a pair of holddowns keep workpieces firmly planted while you work. This jig also doubles as a handy dado and groove cutter.
