The first time I saw a flexible sanding strip in action was while watching an episode of Woodworks going on almost 10 years ago. David Marks incorporates lots of curves in his work and the man knows a thing or two about making them. Since then, I have made numerous sanding strips in all shapes and sizes and my curves are about as perfect and smooth as they can be.
Flexible sanding strips are incredibly easy to make and I get a lot of requests for more information on this little shop helper. All you need is a piece of 1/8″ plywood, some cork, sandpaper, and some spray adhesive.
Cut the plywood to 4″ W x 11″ L (or whatever size you want). Use the spray adhesive to attach the ply to an oversized piece of cork. Use a razor blade to cut the excess cork from the perimeter of the ply. To attach the sandpaper to the cork, use a few quick bursts of the adhesive. The goal is to make a temporary bond so that the paper can be replaced in the future. On the top side of the strip, glue a small piece of scrap on each end for handles. That’s all there is to it!
The world of smoothing curves will never be the same!
