A hypothetical for your ponderment.

A wooddorker finds a bit of spare space in his yard^H^H^H^H shop, and
decides to quickly erect a stout bench from the materials at hand.
Let's say the wooddorker finds some somewhat straight, and somewhat
cheap dimensional lumber at the local BORG and sets out to build a
functional bench from green douglas fir (not really a fir, but this is
common usage and I don't really have time discuss vagaries of the
various conifers for sale locally, though they are an extremely
interesting species), complete with carefully cut/milled/trimmed
square dog holes for a beefy iron bench dog.

And let's further say that as the wood seasons, the bench dog holes
shrink, making it impossible to use the beefy bench in the bench.

*sigh*

DAMHIKT.
