[0036]FIG. 1 is an exploded view of my invention.

[0037]FIG. 2 is an exploded view of the motor assembly.

[0038]FIG. 3 is an exploded view of the housing assembly.

[0039]FIG. 4 is an exploded view of the motor construction.

[0040]FIG. 1 shows an overall view of the “Handheld Drum Sander”. The “Handheld Drum Sander” is composed of four major assemblies. The battery 11 or power supply is a self-contained rechargeable power supply. The battery 11 plugs into a connector on the main circuit board 19 shown in FIG. 3 on Sheet 3 and provides all the power to drive the motor assembly 15. The main housing contains the mounting structure for the battery 11, motor assembly 15, grip 13, circuit board 19 and end cover 9. The two halves of the housing 18&20 are joined together by screws 14. These same screws 14 retain the trigger 12 and the circuit board 19. The grip 13 shown in FIG. 1 is a rubber molded cover that is mounted to the main housing 18&20 to relieve operator hand fatigue caused by the ope...

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a device for the finishing of irregular shape objects by using a hand held drum sander in general and in particular to a self contained power driven device having a novel method of driving and supporting the sanding drum and retaining the sanding substrate.[0003]2. Description of the Prior Art[0004]A sander is a power tool used to smooth wood and automotive or wood finishes by abrasion with sandpaper. Sanders have a means to attach the sandpaper and a mechanism to move it rapidly contained within a housing with means to handhold it or fix it to a workbench. Woodworking sanders are usually powered electrically, and those used in auto-body repair work by compressed air. There are many different types of sanders for different purposes. Multi-purpose power tools and electric drills may have sander attachments. For example, U.S. Pat. Nos. 5,678,292 and 5,957,765 to Kimbel et al. disclose a ha...
