Bridge repair

[Neil Garber]

I have a bunch of middle school students, and the basses they bring are often borderline unplayable. One problem I think I can fix quickly is a bridge where the string slot has been filed too deep. The usual technique of slipping some material under the string to raise it works well enough, but I was thinking that it would be easy enough to glue a new piece of wood there. A triangular insert would be easy to make. I've seen violin bridges with triangular ebony inserts for the the E string. I would use maple. Any thoughts, opinions, warnings or techniques? Thanks.
