building up the bridge groove
I have a young student whose A
string has worn such a groove that the string is now below the
"ridge of the bridge." Is there an acrylic compound or some such
that I can fill in the groove with, that will be harder than wood? I
hate to send him to the shop for a new bridge, unless the expense is
absolutely necessary. I'm stop-gapping with a piece of cardboard in
the groove.

I had a similar problem that I was
able to correct by mixing up some expoxy cement -the kind where you
have two tubes and mix them in equal proportion, just before
applying. I filled the groove with the cement, allowed it to dry
very thoroughly overnight and then lightly sanded off the excess.
This put the string back on top of the bridge where it belonged.
A lot of luthiers use parchment on the A and D strings of
new bridges to prevent or slow down this cutting in process. The
small black plastic sleeves that come with some strings (Pirastro
has them) also help to prevent this bridge groove cutting as
well.

Huh, the things I learn!
I've
never heard of building up the bridge with epoxy. Cheaper than a new
bridge is to have an insert made. The luthier would cut out a notch
of the bridge under the a string and make a piece (usually ebony, I
think) to fit in, raising the string to the proper
height.
I'm rather sensitive to the changing height of the
strings as the humidity changes. I wish we could have bridges like
bass players do, witht he adjustable screws for the height.

adjustable bridges
I've heard that adjustable bridges
degrade the tone a little bit. This effect isn't as noticable on
double basses, but much more so on cellos.

I always use a piece of drumhead
(natural,not plastic)
Make it wet before applying, so you can fit
it to the bridge.
It does´nt affect the sound and prevents
strings to cut into the bridge, - ask percussionists for broken
drumheads......

When I had the A & D drumheads
(that's what he called them) on my bridge replaced, I was told that
parchment isn't strong enough-- what is used on the cello is lizard
skin!

Ever try chamois? Cut pieces of
chamois into little squares - fold them and compress, place in
groove.
The chamois nestles the string nicely, doesn't seem
to affect the sound, adjusts for humidity changes, protects the
bridge and IS INEXPENSIVE.
