With the Whiteside multi side router bit one tool makes both cuts. The multi side cutting profile will effectively be creating a ‘birdsmouth’ joint allowing you to make multi sided objects. The ‘birdsmouth’ joints are synonymous with the making of ship masts. These joints are also common in the joint making of timber roofing frames appearing in many different combinations and sizes. The strength of multi sided object will be maximized with full circle completion.
A great way to join up many multi-side projects like planters, columns, barrels, etc. Very straightforward, this joint requires routing a notch in only one edge of each stave (side). Notching also improves ease of assembly and total glue area.
On 6 and 8 sided objects, the exterior side is cut face up on a router table; 12 and 16 sided objects are cut face down. The same bit (3506) is used for 6 sided and 12 sided objects. Either flush or ribbed (outside corners protruding) construction is possible. Ribbed construction is recommended with 12 and 16 sides because the interior leg of the notch will be very small when made flush. Outside corners on ribbed construction can be cut or sanded down for flush appearance if desired.
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. This will put the inside corner of the notch in the centre of the stave on 6 sided flush projects. The inside corner will be below centre (furthest from exterior side) on all others. Allow extra stock to experiment and set corner height as desired. Move notch towards exterior side (raise the bit) to increase rib size (amount of outside corner protruding). Move notch away from exterior side (lower the bit) to decrease amount of rib. Note that bit adjustment is reversed on 12 and 16 sides since those staves are cut face down.
RPM at 16000 as a starting speed and adjust as required.
Compatible with CNC and table mounted routers with a guide fence.
