There are numerous resources on constructing epoxy resin river tables. However, virtually all of these designs have a strip of resin running parallel with the grain of the slabs on either side. This reduces or eliminates issues with wood movement since the wood/resin bond is perpendicular to the direction the wood expands.
Has anyone seen or used resin bonded in a parallel direction with wood movement? Imagine bonding resin to the endgrain of a table top, like a breadboard. Would the movement of the wood across the top destroy the wood/resin bond? If the bond is strong enough to keep the ends from moving, would you get strange cupping or other stresses as the middle or other end of the wood pieces try to move? Does using a dovetail or box joint improve the bond strength?
My application is attached. This would be the front of an entertainment console table; the resin center would actually be the front of a built-in subwoofer enclosure. Not pictured in the attachment are a top and bottom of the table to help support the joints.
In all my searching I haven't seen anyone try something like this. Unfortunately it's not a simple exercise to just test the joint since it's hard to artificially induce seasonal wood movement. Appreciate any thoughts.
