Dear members,

this summer I am helping a  young student making her own harpsichord.
She works on a six-foot-Ruckers-style single, 8' 8'. The case has been finished and we are glueing up the soundboard right now.

SB material is alpine fir.

In oder to prevent the finished boards from cracking up, I always chose cold and dry winter days to work on the SBs of my own ten harpsichords.
But the young lady will have to present a playable instrument by october. (final painting, decorating, the build of a stand - even lids - may follow later).

So: Is there any way to dry out the thinned soundboard in summer here in Germany?
Bright sun?
Sauna?
Ventilation?

Unfortunately I do not have access to professional gear such as drying chambers or things like that.


Greetings from river Rhine


Michael
