Cracked bridges

[Zen Reinhardt]

Hi Joel --

Been there done that.  Thanks for the advice anyway.  Instead of taping the
mylar to the bridge, I drilled guide holes close to each end and pinned the
mylar in place.  Then I marked the bridgepin holes with a single-needle
voicing tool.  (Doing a pattern with the pins in place would have been an
excercise in futility -- so many pins were so badly blown out of their
original places not to mention the differences in height and angles because
of the problems.)
