Hall Table

here's a handy site with a calculator - not sure how accurate it might be,
but might give you some idea:

using this, a 11" wide maple board with a 14% moisture content (~75% RH in
ambient air) that changes to a 8% moisture content (~50% RH environment)
will contract about 0.22".

Depending on where your skills and shop equipment are...

Think about cutting your own veneer, and laying it up over a stable
substrate. The special wood goes further, and it doesn't move nearly as
much.

This will possibly give you an excuse to upgrade your bandsaw, too.

Patriarch,
not quite there yet, but closing in on it...

Thanks for the info and link Mike. Nifty calculator. I think I know what I
want to do now.
