None of the above !
Birch Plywood, .75"
The wood was actually scrap from building my lathe cabinet (pic in my album). I made it a month ago, and I am using it every day. Woodworker friends, and even the people at the turning club have not guessed it correctly !
Shellac at 400 grit, sanded to 2000, and five coats of MinWas PolyCrylic. Yesterday I put some TSW on it, and buffed used my new high-tech buffer.
