These complete and detailed plans are for constructing a purfling/binding cutter router used to create binding and purfling channels on acoustic guitars. The attachment can be mounted on any laminate trimming router. Use of this device was demonstrated in both the guitar making book and the 10-DVD box set. The two-piece attachment is fully adjustable for both the depth and height of the cut and capable of cutting both the purfling and binding channels.
When cutting channels for the bindings it is recommended that they are cut in multiple passes since this is a lot of wood to remove in one pass with a small bit. The purfling channels are typically smaller and subsequently much less wood is being removed so these channels may be cut in one pass. A 1/4″ down spiral bit is recommended for best cutting results.
