Making identical flutes of the same length and depth and spaced evenly around the circumference of a tapered or cylindrical spindle such as a table leg requires a lathe, router–and one more thing–a precision jig. Mounted to your lathe, this accommodating shop project features a router platform that adjusts parallel to the workpiece surface for flutes of a consistent depth from one end to the other. Attached to the platform are T-Track runners that support sliding stops. These lock in place, letting you create flutes of a repeatable desired length. Another locking mechanism secures the jig’s base to the lathe’s ways. Here’s how to build the jig and put it to work.
