Monroe If you make a two sided base, which you can still do with that scrap Jim mentioned, you can space two prongs wide, and two narrow, so you can measure whatever angle relationships you like, and have it your way all around. Take all measurements with the same set of prongs, for continuity. The Wixey, or Beall Tilt Box, is more versatile than the bubble gage because it will measure bearing on vertical pianos as well, with the same setup.
