Edge Sanding

Figure 18-4. Work this way when sanding edges. The setup assures that sanded edges will be square to adjacent surfaces.

Most edge sanding is best done with the machine in the vertical position (Figure 18-4). The setup assures that sanded edges will be square to adjacent surfaces. Move the workpiece slowly, but keep it in constant motion. The drum will continue to sand if you hold the workpiece still and this will cause indentations that will spoil the edge. Move the workpiece from left to right, against the drum's direction of rotation.

Sanding operations will be most efficient and abrasive materials will last longer if you do initial cutting so there is the least amount of material for the sander to remove. When you are doing a lot of sanding, occasionally adjust the drum's vertical position so you will be using all of the abrasive surface.

Figure 18-5. To sand internal edges, position the stock before extending the quill.

Internal edges are sanded in a similar fashion, the only difference being that you position the work piece before extending the quill (Figure 18-5). The drum sander's position is maintained by locking the quill.

Figure 18-6. Sand straight edges as shown when you wish to sand workpieces to an exact width.

You can smooth straight edges freehand by passing them across the drum; but a more efficient technique, when stock width permits, is to work with the rip fence as shown in Figure 18-6. The drum's depth of cut must be very light, only enough to smooth the edge. When the fence is situated between the drum and the way tubes, the pass is made from right to left. This setup is also used to edge sand any number of pieces to exactly the same width.

The same setup can be used if you work with the shaper fence. The amount of material to be sanded off is controlled by adjusting the infeed fence as you would when doing a shaping cut that removes the entire edge of the stock. There is no limit to how wide the stock can be when you are using the drum sander/shaper fence arrangement.
