Drum Sanding

 

Flap Sanding

 

 

 

 

 

 

Drum sanding is perfect for performing sanding operations on edge contours. Inflate the drum to the desired air pressure using a hand pump. Use a soft sleeve and lower pressure when sanding contours with rounded or soft edges. A hard sleeve and higher pressure is desirable when the edge is to be sharp. Be certain to mount the abra- sive sleeve on the drum so the direction of rota- tion of the sleeve will match the spindle rotation of the machine you are using.

Figure 7 shows a typical sanding operation. Remember when sanding, the spindle is rotating towards the operator.

Operating this equipment has the potential to propel debris into the air which can cause eye injury. Always wear safety glass- es or goggles when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glass- es you wear meet the appropriate stan- dards of the American National Standards Institute (ANSI).

Flap sanding is useful for sanding rounded or spherical shapes. With the flap sander mounted on the left hand spindle, the abrasive side of the individual sanding flaps will be rotating toward the operator. It is generally best to introduce the workpiece to the downward side of that rotation for the best control of the sanding forces. Figure 9 shows a typical sanding operation.

The flap sander is supplied with 120 grit paper installed. The abrasive sheets can be replaced with different grits if needed. See the Maintenance section for detail on replacing the sandpaper.

DO NOT attempt to operate this machine before completing the assembly and adjust- ment instructions. Be sure that the switch is off and the cord is disconnected from the power source at all times until assembly and adjustment are complete and you have reviewed all safety guidelines. Serious injury could occur.
