Tightbond Creep

FWIW

I've seen a fellow in Oslo pull out hide glued soundboards in the course of a
demonstration for a convention class. He does this on a regular basis as he has
a particular view about how to handle soundboard cracks. He thinks that if you
are first going to fix a crack, then you might as well do it as part of a
larger job of upgrading the panel. So he pops (litterally) out the panel, pops
off the ribs, and pushes the panel back together. Reinstallment of the ribs
allows him the nicety of being able to machine crown them a bit to add to panel
strength. If he does need extra material for the panel, he puts it on one of
the edges.

Another fellow I know in Amsterdam also seems to have no trouble removing
panels glued with hide glue. He's one of these fellows who are fond of using
the old panel with new ribs. Works well, lasts a long time.

Not being a soundboard installer myself, I cant speak from experience mind you,
but when I see such things done before my eyes... I gotta come to the
conclusion its more a matter of knowing how its done then anything else.

That being said..... just how many times is it likely that a rim will get a new
soundboard installed ?? If you are installing a new panel in an old instrument
? Seems unlikely that this issue should ever come up again in the life of that
instrument... or what ?
