Methinks this
notion of wood movement has taken on a set of legs of its own.

Oh yeah, it is just an urban myth that several hundred years of
craftsmanship have developed specific building methods to help avoid
the problems associated with it.

The tools like the shrinkulator are just for kicks

The academic volumes on the subject are all just whooie like this one
from the feds
Moisture Relations and Physical Properties of Wood

Make up a nice flat panel out of a few pieces of oak. Lay it flat om
the concrete floor in your garage for 24 hours. Tell me what happens.
You can coat it with poly or lacquer first but then it might take 48
or 72 hours before it starts to roll up.

Or just lay down a piece of 3/4" plywood.

Build a table top out of any wood about 30" wide and add breadboard
ends using a wide tennon\mortise glued all the way across. It might
take a year or two but you'll see the breadboards remove themselves
from the table top.

None of the comments above address my original comments. Oh well...

If you are the original poster, I believe the consensus of 1000's of
years of wood working experience and the poster to your question is it
is a bad idea.
