[CAUT] Bass bridge removal

Instead of trying to put epoxy in from the top, if you can, put masking 
tape on the crack, and turn the piano upside down. Then fill the crack 
with epoxy form underneath. I use Webb Phillips Wood Rebuilder, which 
can be thinned down to allow it to penetrate into the crack.

Subject: [CAUT] Bass bridge removal

Hi List,

On a small grand we're rebuilding there is a crack
that runs along close to the side (the rim side) of
the bass bridge and actually under the length of the
bridge.  SB replacement is not in the picture but
epoxy in the cracks will be used.  We've dried the
board down.

Do we need to pull the bridge in order to secure that
crack that is underneath the bridge?  If so, what
methods do you recommend?  There are four screws
underneath, and I know some form of moisture and heat
will soften the glue joint, but I would like some
specific recommendations on this.

The narrowly designed bridge has a small "apron"
offsetting it for longer speaking lengths and or
giving it a connection to a more flexible part of the
SB.

Thanks.

Bob Hull
