Types of Drum Sanders

Figure 18-1. The drum sander is 2-1/4" in diameter and 3" long. It mounts on the Mark V main spindle or the belt sander auxiliary spindle.

The drum sander is 2-1/4" in diameter and 3" long (Figure 18-1). Abrasive sleeves are easily mounted or removed by loosening the hex bolt that is in the base of the drum. This action relaxes or expands the drum's rubber cylinder to either grip or release the sleeve. The grits are available in coarse (60#), medium (80#), and fine (100#)

Figure 18-2. The drum sander is used with the drum sander/shaper insert. Model 500 is shown.

The drum sander mounts on the Mark V main spindle or the belt sander auxiliary spindle. The special shaper/drum sander insert (Figure 18-2) is used for most operations. The shaper or rip fence, when used with the drum sander, can accurately control the drum's depth of cut when it is used to do edge sanding on straight edges.

Smaller drum sanders are available in sets that include drum diameters of 1-1/2", 1", 3/4", and 1/2". They are mounted in a three-jaw chuck or 1/4" routerchuck. Warning: Smaller drum sanders should be used with the special insert shown in Figure 18-3. The special insert provides support for the workpiece.

Figure 18-3. Make the special insert and drill the mounting holes by using a drum sander insert as a pattern. All disks have a 2-1/2" outside diameter and: (A) a 1-5/8" inside diameter; (B) a 1-1/8" inside diameter; (C) a 7/8" inside diameter; or (D) a 5/8" inside diameter.
