Good quality violin, viola and violoncello bridges are relatively easily damaged and expensive to
renew.
They are expensive because, in addition to being made from a costly, especially dense type
of maple wood, each one has to be specially fitted and customised for your instrument.
Each bridge can take several hours to carve and as the special bridge wood is
expensive and the fitting labour intensive, the eventual cost is high.
Violin, viola and cello bridges are very slender, considering how tall they are and
the enormous load they have to bear, so care is very important.
The back face of
the bridge (that facing the tail piece) should be at 90° to the belly of the instrument,
even leaning very slightly backwards is normally OK. As the instrument is tuned the
strings have a tendency to pull the top of the bridge forward (or backward if the
tuning is done mainly with the fine tuners on the tail piece) and it is crucial
that the bridge is straightened after tuning. It is very easy to check that the
bridge is straight and it is recommended that this is done daily. The string
grooves in the top of the bridge are lubricated with dry soap or graphite
from a pencil so the top of the bridge can be gently moved to ensure that it is
standing upright. If this movement gets more difficult over a period of time,
re-lubricate the string grooves. Do this one string at a time, do not slacken all
the strings off at once.
If you care for the bridge in this way it will give many years of service.
