Bird Mouth Joinery: the 8-side router bit

Bird mouth joinery permits easy construction of unique and unusual eight-sided vessels via simple edge routing. The 8-side router bit is shown to produce lozenge, diamond, oval, square, rectangular and trapezoid shapes, as well as regular octagons. Construction of a napkin holder and a jewelry box from walnut, maple and/or holly demonstrates use of this technique. ************** For further information on bird mouth joinery projects:
