R. Woudsma:   The Loonsong Instrument Company Home Home

In this shop page I describe various tools, jigs and machines that I have designed or modified from existing designs and constructed to make the process of instrument building easier or more precise

The Joiner

Instrument backs and sides usually come in book-matched halves that when joined together form a pleasing symetry of the wood grain or wood colour variations.

A joiner is needed to apply pressure to the two halves as they are glued together to form the full back board or front sound board.

This joiner applies top pressure to keep the two sides aligned and applies side pressure to make a strong edge bond between the edges of the two halves of wood.

The Thickness Sander

The thinkness sander finds a great many uses in the guitar shop. Primarily, it is used to sand all raw front, back and side woods down to a specific thickness; usually .10” to .12” for backs and .08” to .11” for fronts and sides.  

The use of thickness planers are not recommended at this fine level of wood thicknessing.

The sander uses a kit-bought velcro-loop covered roller and two bearing blocks driven by a standard 120vAC motor.

 3” wide velcro-covered sandpaper is rolled, cork-screw style onto the roller to form a rotating sanding surface of about 10 inches long.

The roller is almost completely enclosed in a windowed box with an opening on the side to allow a shop-vac to remove the dust.
