Thinking about structural integrity of wood. Dee Hays' compelling
observations about humidity vs. temperature.

Her knowledge lends perspective on an issue most of us deal with using
anectdotal information.

A question...

Most wood that has been harvested develops cracks. I presume that is
because what was circulating through it when it was alive, sap, is no
longer present to repel the drying and shrinking process due to changes in
humidity. In most circumstances the cracks are of little significance.
ie. My house will not collapse because of cracks in the wooden [spruce]
studs.

Clarinets are required to be somewhat air tight. If a clarinet cracks
would it be desirable to 1. Try to close the crack. or
2. Fill the crack with a not too inflexible filler such as epoxy?

before pinning.
