Leo Schenkelaar has made up this sanding thicknesser. He described his tool in the Bouwbrief, the Dutch magazine for professional musical instrument makers. The sanding thicknesser is extremely good at thicknessing small pieces of wood (sizes that are too short for an ordinary thicknesser) and making veneers of less than a millimeter.
The sander consists of a bottom plate (1) under which the engine (6) has been attached. The top plate (2) is hinged on the bottom plate, and can be screwed up and down. The sanding drum (4) with protecting shield (8) is fixed between the bearing (5) on the sides (3). It is important to make the top and bottom plate dead square.
Test the thickness by pushing a piece of scrapwood under the drum.
That 's all there is to it!
