Abstract

A manually adjustable combined edge and end fence for a belt sander comprises a first sanding fence member coupled to a second sanding fence member extending transversely, and preferably orthogonally, to the first fence member. The second fence member also functions as an adjustable slotted table mount to the belt sander. The first fence member can function either as an end stop or a side fence by being rotated 90 degrees in a plane parallel to the sanding surface of the belt sander. The slotted mounting arrangement enables continuous adjustment of the assembly along the axis of movement of the sanding belt, including adjustment to locations of the first member beyond the end of the belt for accommodating work pieces of long length. The invention additionally contemplates a wrench retainer accessory, use of single sized adjusting bolt heads, a support table and motor mount arrangement providing improved rigidity, and an improved dust removal arrangment.
