Short video excerpt from the New Yankee Workshop detailing the hanging tool chest of piano builder H.O. Studley. This is some of the finest wood craftsmanship I have ever seen. Henry Studley built this tool chest over the course of his 30-year career at the Poole Piano Company sometime in the 19th century.
