Dear Lou,

The question of durability involved boiling sample coupons then trying
to peel them apart.

Based on musical instruments assembled with low-tech hide glue, when
properly sealed, the moisture content of the wood -- and the strength
of the joints -- can remain stable for a hundred years or more. By
comparison, when not subjected to an outside agency such as heat, mold
or moisture, the joints produced by virtually all modern-day adhesives
are relatively ageless.

When purchasing someone else's project a detailed inspection by more
than one pair of eyes is always the wiser course. We now have more than
seventy years of experience with epoxies as an aircraft glue. There is
no inherent fault in using epoxy versus some other adhesive. What
changes is the inspection criteria and that information is best
supplied by someone familiar with the particular adhesive used in the
project.
