Hi! I have a cello with a hard maple bridge, as well as a spare graphite bridge. The bridge pushes the strings away from the body, as you can see in this picture: http://upload.wikimedia.org/wikipedia/commons/d/da/Cello_bridge.jpg The problem is the following: The spare graphite bridge is too massive, resulting in less treble and less overall sound volume. So, I want to make it thinner. Hopefully, it will be able to do the same job as the maple bridge, while less massive. What is the approximate thickness needed to make the graphite similar in strength to the maple one? I don't know anything about the quality of the graphite in my spare bridge, so just assume it is "run-of-the-mill" graphite, if such a thing exists. Anyone care to make an informed estimate? EDIT: Btw, the graphite is "pure", i.e. contains no embedded fibres of any kind. Sort of like the inside of a pencil.
