I’m building a pool table that will have a live edge apron, about 8 inches wide and close to full 8/4 thickness. I’ve flattened the outward facing side of each piece and have jointed a flat edge opposite the live edge 90 degrees to the flat face. I started to get the planer ready to flatten the non outward facing faces but then it occurred to me that maybe there is no need since these faces will never be visible and I’m using T Nuts for the joinery. Is there any reason I need to flatten that other side? If it matters this is birch from a tree I cut down last year and had the 8/4 slabs all kiln dried. Thanks for any ideas
