Description

Also known as a 'birds mouth" bit, a Multi-Sided bit is a great way to join a wide variety of multi sided projects, such as planters, columns, and barrels. Very straight forward, this joint requires routing a single notch in one edge of each stave (board). The notch improves ease of assembly and total glue area.

Once assembled, projects can be left flat sided, turned, planed, or sanded to the desired shape. Bits should be used in a router table with a fence. Whiteside 3508 works for 8 sided objects with material up to 7/8" thick.

Either flush or ribbed (outside corners protruding) construction is possible. If desired, outside corners on ribbed construction can be cut or sanded down for a flush appearance.

Location of the inside corner of the notch (i.e. vertical bit adjustment) is important for final finish appearance. The outside leg of the notch (closest to the exterior) should be the same length as the stock thickness for flush construction.

The inside corner will be below center (furthest from exterior side) on all others. Allow extra stock to experiment and set corner height as desired. Move notch towards exterior side (raise bit) to increase rib size (amount of outside corner protruding). Move notch away from exterior side (lower bit) to decrease amount of rib.
