I am making a clamshell box out of 3/4-in hardwood. Both halves of the clamshell are pocketed almost all the way to the opposite face. The parts come out beautiful but when I go to put them together and they are not flat enough to create a good seam. Unfortunately the halves of both faces either have a ridge for the parts indexing together or a bunch of holes for inserted magnets. It's not as simple as sanding the two halves flat in the post processing.
I've done a lot of reading and video watching on both resin and epoxy impregnating and was wondering if the easier of the two (resin) would both eliminate the moisture warping issues that plague woodworkers everywhere but also would relax the apparent internal stresses that could also be contributing to the warping.
Another thought that crossed the mind regarding epoxy impregnating - could you draw a vacuum long enough to impregnate the wood but not long enough for the epoxy to cure? That way the wood blanks could be removed from the epoxy so that they do not become entombed.
Appreciate the thoughts guys.
