A 1/2" hole was drill through the center of the recess and followed by an application of polyurethane adhesive to receive the 3/8" T-Nut. This will be done for all three leg sets. Makes for a much stronger connection. NOTE: Only use a very small amount of this type of adhesive in the the hole itself before inserting the T-Nut. Polyurethane adhesive foams up as it cures and could possibly clog up the threads in the T-Nut. A very tough job to clean up, so be careful.
