I have come up with a bench top version of a sanding block that I call the Locking Sanding Block. I say “locking” because the way it’s designed the sandpaper is locked into position and won’t come loose, it stays taught even after a long period of sanding. (Click on image to enlarge pics).
It is built using baltic birch and walnut. The size of the block takes advantage of a 9″ x 12″ sheet of sandpaper with three strips of approximately 3″ W x 7″ L of sanding surface. Even though it’s simply a rectangle block it feels comfortable in your hand during a sanding session.

Showing all of the parts of the Locking Sanding Block you can see how simple it would be to change different sandpaper grits or replace a worn sandpaper with a fresh one. I have labeled each sanding block with the grit installed for quick reference.
I have put together free plans for making one of these sanding blocks here: www.bit.ly/Z9SaoC
