Here's an example of what an epoxy repair to a bridge can look like. The
owner thought the tech who did this was an outstanding technician. Note how
uneven the pins remain, and the irregular angles of the strings.

Subject: Hairline cracks in Treble Bridge


 
I have an 1890 Sohmer Upright (55").  After having it tuned I started
hearing an annoying vibrating sound out of the F Key above middle C.  My
tuner came back out to investigate and found some hairline cracks in the
upper part of the treble bridge.  He called a few people whom he trusts for
bridge rebuilding.  His plan was to remove the half of the treble bridge
with the cracks and send it off to be used as a model to rebuild a new one
and put the new one in for me.  But everyone was booked well into next year.

So he found out about a gentleman who does Epoxy repair.  He himself has
never done this type of repair with epoxy but after speaking with this man
and watching his video he feels confident that he can repair the hairline
cracks with epoxy.  I am wanting to know the pros and cons to doing such a
repair.  Can you also tell me the pros and cons to removing the half of the
treble bridge with the hairline cracks and sending it away to be used as a
model to build a new half and putting in a new half bridge in instead. 
I have recently put $523 worth of repairs into this piano.  I am wondering
if I should even do the treble bridge repair and if so which way to go.  The
tone in this piano sounds really great to me and my daughter.  I hear so
many bad things about newer pianos not holding up well.  So could any of you
advise me on this matter.  I am concerned about the epoxy method causing any
problems with the tone and sound.  Plus will the pins be glued in?  Would
that cause problems later on?
Thanks.
