I used to fix Brunswick racks for a room near my old home in NJ. The factory glued joints failed often (6 joints each rack). I cleaned the pieces up with a triangular file, used two part epoxy and clamped it with a window frame type strap clamp. I removed one of the metal brackets of course. The metal brackets hold the strap off the wood so the epoxy doesn't get on it. Wipe off squeeze out while wet. Sand smooth after drying overnight. I used wipe-on polyurethane to seal any exposed wood to eliminate splinters. I cleaned them first to remove the residue build-up inside with a Magic Eraser. Waxed them after paint was dry.If anyone needs more info on this technique, please PM me. Every joint I repaired did not fail again, 3 years until room closed. Saved that owner a ton of money, because he kept buying Brunswick's new ones at first.
