I made this fixture for my drill press to cut the slots for biscuit joints. The fixture holds the workpiece and acts as a guide for a 5/32-in.-wide three-wing slot cutter mounted in the drill press chuck. To use this method, make sure the router bit bearing is mounted above the cutter and adjust the quill so the cutter is positioned on the centerline of the workpiece. Then, place the workpiece in the fixture and tighten the wing nut on the adjustable cam lever arm, so the cam can be used to lock the workpiece securely into the fixture. Now, with the drill press running at its highest speed, push the assembly into the turning cutter from right to left and let the bearing follow the semicircular cutout to rout a biscuit slot. Incidentally, this same fixture can be used on a router table if you move the bearing to the other side of the cutter.
