I’m looking for suggestions for dealing with a large glued-up slab that has cupped across the narrow dimension. It is white oak, 26” wide by 72” long by 1 1/4” thick, made of three boards, with the ring pattern alternated (bark side up, bark side down, and bark side up). It bows 1/16th of an inch at the midpoint. I can’t plane it any thinner—the other table top has been constructed, and the two tables will be side-by-side.
1. Should I attempt to correct the bow before assembly, or depend on the casework beneath to straighten it out? (The frame is fairly heavy, and much of it is concealed. I plan on using pocket screws to mount the top.)
2. Is there a worthwhile method of clamping the wood for a while? Wet one side? Expose one side to the sun, to dry/shrink it?
Any suggestions would be appreciated; re-making this top is going to get expensive.
-- Now, where did I put those bandaids?
