Double sided head-stock surfacer

This is a good use for one of the common 4"x36" bench top belt sanders. If you plan to make your own necks this machine not only thicknesses the head stock but also refines the slope angle and finish the veneer side. There's many ways to construct it -- as the saying goes a picture is worth a thousand words. The veneer side surfacer is simply a stationary ramp constructed out of MDF cut to proper angle -- note the ledge on both sides to keep it clear of the belt.
To add accuracy and control I made a sled to contain the head-stock -- it fastens to the HS with three set screws run through brass threaded inserts, a spacer protects the neck
The ramp is made of two pieces of MDF they are hinged together on the inside edge. Channels on each side are made of two layers 1/4" Masonite. Since the bottom of the sled is also 1/4" it works like a drawer slide.
Thickness is controlled with a height adjuster screw run through a "T" nut. Several rubber bands are used to apply tension to the hinged plate
The sander is mounted on a board -- then the frame work is attached to the board. The frame design will vary based on the brand of bench sander that you use, but the concept is the same.
