A client paid for this project as part of his home entertainment system. Following turning, the client immersed the wood in a specially fabricated steel vacuum drum. Instead of using pure tung oil which he thought "too expensive", he decided to save money and used hardware-store spar varnish, a foul-smelling finish, in an attempt to make the wood translucent, similar to Cook Island / Norfolk Pine. It told him the maple would not become translucent but he persisted. The speaker came out with such chemical smell that it was ruined for use in any home. The person that paid for this project had more money than common sense. He paid me $6000 and gave me an opportunity to stretch my talents as a wood turner. My wife recorded the video, thank you to her. Part 1 of this video shows more technique.
