Grooving a Post—No Problem With This Jig recently made a four-poster bed with 6-ft. high turned posts. I wanted to cut longitudinal flutes in the turned sections of the posts, but I realized neither my router nor my shaper could be adapted to the task. They'd work fine for cutting flutes on a post shaped like a straight cylinder, but I had turned my posts with gently curv ing contours along their length. I needed a flute-cutting setup that would follow the contour of the post as it cut flutes of uniform depth.
To solve this dilemma. I built a fluting jig so I could cut the flutes with a commerciallv available router bit (part #01361 available from Cascade Tools, Inc.. Box 3110, Bellingham, WA 98227, 800-235-0272) on my drill press. The router bit has a carbide fluting cutter and two pilot bearings on it that ride against the profile of the post. The bearings guide the cutter as it forms semicircular flutes '/a in. deep and XU in. wide. The jig I made holds the post horizontally so you can push the post against the bit spinning in the drill press chuck. Cutting a flute is similar to running a piece of stock past a router bit on a router table. (The bit's shaft isn't long enough for this method to work in a router table.)
The jig holds the turned post between centers like a lathe does. (See Fig. 1.) I added a simple indexing device (called a "dividing head") to the jig that enables you to rotate and lock the post in equal increments to
