Chamfering tool and drum sander
View Patent ↗A device for chamfering and sanding is disclosed. The device comprises a cylindrical body containing a hollow cone lined with sandpaper attached to the surface of the cone with adhesive. Two corners of the sandpaper are inserted respectively into two slots contained in the sidewall of the cone to further hold the sandpaper in place. The device comprises a shaft attached to the bottom of the device for clutching by a drill press or a three jaw chuck. As the device rotates, objects that require bevelling or sanding are inserted into the cone and pressed against the sandpaper. A sandpaper sleeve is attached to the outer surface of the cylindrical body that may be used for sanding and smoothing.
1. In combination:
a device comprising:
body, said body having a cylindrical outer profile defining an exterior surface and a conical interior defining an interior surface with an internal surface area; and
a shaft attached to said body,
wherein said body has a first slot and a second slot through said body and being open to said interior surface and to said exterior surface, said body being limited to having only said first slot and said second slot, said first slot and said second slot being located equidistant around the interior surface of said body to bisect said body into two equally sized parts; and
an article that is generally flat, has a rectangular perimeter and has a sanding medium on one of a first side and a second side, wherein said article is folded in half whereby the sanding medium is inwardly facing;
wherein:
said body receives sanding medium within said first slot and said second slot;
said article takes a conical shape within said conical interior;
said second side of said article completely covers said interior surface of said body to peripherally continuously expose and support a conically oriented amount of sanding medium, and
said article passes through said first slot and said second slot whereby said article is symmetrically held within said body to balance the weight on said body as said body rotates.
2. The combination of claim 1 wherein said second side of said article has a pressure sensitive adhesive affixed thereto to secure said second side of said article to said interior surface of said body.
