Wood Parts Tumbling to Remove Flashing

Common practice to remove flashing and sand wooden parts is by hand. Sandpaper or sanding wheels can be used to effectively clean up parts one at a time. A more efficient process (especially for large quantities of parts) is to use barrel tumbling.

This picture shows a before (left) and after (right) of a walnut wood part with heavy flashing, excess material on the edges and a rough cut surface finish. This is probably an extreme example; however, a simple barrel tumbling process created the surface finish on the right.

This part was tumbled with Hardwood Media and a small amount of 120 Mesh White Aluminum Oxide overnight. The result is a smooth surface finish with rounded edges and no excess material.
