Building Your Own Reusable Sandpaper Blocks

sanding blockSanding is a precision-based art that requires a lot of careful planning and the right tools. Creating your own reusable sandpaper blocks is one way to simplify this sometimes exasperating project. Follow this simple woodworking tip to create blocks you can use again and again for multiple projects.

Tools Necessary

This simple project doesn’t require many tools. I was able to use a couple of scrap pieces of scrap plywood for each block I made: try to find scraps at least 3/4-inch thick for each block. Four total sanding blocks are preferable: in that way, you can have a block for very fine sanding, slightly rougher, fairly rough, and very rough sanding.

Cut the Blocks

Take your plywood and cut a block about large enough to fit your hand. I think that 2 x 4 inches is large enough for most people. The kind of saw you use doesn’t matter, but make sure to square up your cuts with a t-square and to double-check each measurement. Sand the corners and edges to avoid splinters during the rest of the process.

Glue On Cork Wood

Now, spray wood glue on one face of the board and apply a similarly sized piece of cork wood. Flush it with the edge of the block with a knife and let it sit for half an hour. Some people like to glue their sandpaper directly to the board, but we’re going to adapt that idea to make it reusable with multiple pieces of sandpaper.

Making it Reusable

Place a piece of sandpaper against the cork wood face and add staples to each corner to hold it down. Avoid sanding with the corners to keep your wood free from staple scratches. Remove the staples when your paper is free of grit and staple on a new piece.

Now that you’re finished with your blocks, try them out on your next project. You’ll be surprised how much easier it is to get the smooth and gentle feel that you desire.
