Building a Better Back Scratcher - Forming and Finishing


Lesson 4 has students forming and finishing their bent-wood back scratchers and completing this PBL project. This series of lessons introduced students to differing tree species, grain orientation and steam bending.


This lesson has students taking their bent-wood back scratcher blanks, and completing the forming and finishing operations to conclude this project. Upon completion, students may, well, scratch, or pat themselves on the back!

Students will learn about proper sanding technique and use the band saw to form the handle. They will use a simple wax finish to complete the project, and learn about the hazards and benefits of oil and water based finishes, in addition to learning which finishes are food and child safe.
