Abstract: An apparatus including first and second sections of a sanding block slidably interconnected and adapted for use with a continuous belt, and a resilient member interposed between the first section and second sections such that the resilient member both selectively repels the first and second sections one from the other while securing the first and second sections in a desired position relative to one another. The resilient member is rotatably connected to the first section of the sanding block such that the resilient member moves between alternate rotational positions. The resilient member produces variable pressure on the second section of sanding block depending on the rotational position of the resilient member. The resilient member includes a lever for securing the second section of sanding block in a position relative to the first section of sanding block.
