ABSTRACT:
A hand sanding block is formed with two blocks, which may be of equal or unequal lengths of like cross section and disposed in coplanar relationship with opposed inner ends. The blocks are freely movable towards and away from each other almost to the point of separation, by means of a pair of spaced dowel pins projecting from one block for telescopic engagement in corresponding spring loaded sockets in the other block and are normally held apart in spaced relationship by the springs in the sockets. For mounting and removing an endless sanding belt the blocks are pressed together so the inner ends are in abutting relationship and once the belt is in place, the holding pressure is released so the blocks can move apart to provide tension on the belt. The block with the socket has two precisely placed holes for screws to be inserted near the forward end of the internal springs holding the spring ends in their sockets while at the same time the dowel pins, are securely glued in the opposite block, therefore preventing the total separation of the blocks at any time.
