soundboard drying speed

[Bob Hull]

When you are preparing an old soundboard for repairing
cracks and refinishing, perhaps for coating with epoxy
to reinforce, is a slower, gentler drying speed better
for the board?  Can making a board to desorb too
quickly cause fiber damage or other damage?  

When drying out an older board my monitoring rule for
the heat is that I don't let a board get too warm to
the touch.  I used to let it gently dry for a couple
of weeks and see the cracks open up and stop
expanding.  However, I would like to speed up this
process if possible.

I have used various methods: heater bars, lamps and a
dehumidfier.

Comments please.

Thank you.
