Cutting rosettes on the drill press
You can cut decorative rosettes by modifying a drill press fly cutter with a beading blade from a table saw molding head.
Notch the fly cutter arm to accommodate the beading blade, locating the cutter about 1 inch from the end of the arm. Make sure it fits securely in the notch so it cannot shift during use. Bore a hole through the arm and use a bolt, washer, and nut to fasten the blade in the notch with its flat face toward the direction of cutter rotation. Set your workpiece on a wood base with stop blocks to hold it securely. Clamp the setup to the drill press table, aligning the center of the fly cutter over the center of the stock. Turn on the drill and lower the quill until the blade lightly contacts the wood. Continue cutting until the rosette has the profile you want.
