ABSTRACT:
A rotary cutting and finishing head of the flail type can use common commercially available sandpaper or emery cloth or other sheet material. A hub of the type rotatable by drill press or hand drill, mounts, in plane, uniform length and width strips or ribbons of any of these materials on slotted tube posts coaxially fixed to the hub. Each slot is of a size to capture a fixed end of a respective ribbon on assembly. In one version, every second post is provided with a ribbon. The ribbons are then wound in a substantially circumferential direction in and out among the posts, the odd posts being merely supports for the staggered partially overlying ribbons. On rotation of the hub at high speed, when the flail end of a ribbon wears from flexing at a post, it may part and release a fresh length or flail end at adjacent location. Alternately, fresh lengths of ribbon may be deployed manually by cutting off or tearing off worn flail portions. In another version, similar in part and that is preferred, a drop-in type ribbon supply is provided. Paint can be removed from soft aluminum as thin as 1/10 mm without distortion of the aluminum. An embodiment for wet operation is also disclosed, and a reversible live handle.
