A year ago, I built my son a checkerboard for Christmas. After gluing
up the strips/squares, which were 1/4" thick cherry and maple, I glued
it down to a chunk of 3/8" plywood for stability, and edged it with
tiger maple. Total size is about 16" square.
A couple weeks after bringing it into the house, it started to warp (concave up), as
the maple/cherry dried. (D'oh! I don't usually have this problem, due to the damp
Anyway, I'd like to fix the warp. I'm thinking I'll take a router to
the back side and eat away all the plywood inside of the edging, down
to the hardwood. I'll cut another piece of plywood to size, and after
allowing the backing and surface to acclimate inside for awhile, glue
them back up.
Any problems with this approach?
