ABSTRACT:
The invention comprises an attachment for a portable hand-tool for the dressing of lumber to obtain roughened or saw-sized surfaces. The attachment comprises a circular disk having a hub to attach it to a portable rotary drive such as a rotary hand-grinder, and a rim on the side of the disk opposite the hub. The rim has a recessed groove to receive a portion of a band saw blade at a depth exposing only the gullet and teeth of the blade. The groove is spaced approximately 1/4 inch from the outer edge of the rim. The tool is used by making multiple passes across the surface to be roughened or saw-sized, permitting on-site saw-sizing of lumber.
