Disassemble gently, label parts, and clean old glue with warm water or steam, preserving fibers. Apply fresh adhesive, clamp with even pressure, and verify squareness. For worn holes, use hardwood dowels or epoxy sleeves. Patience here prevents creaks, wobble, and repeat failures under everyday loads.
Color-match filler carefully, testing in an inconspicuous spot. For deeper damage, inlay a dutchman patch with grain oriented correctly. Sand progressively, avoiding dips, then blend with shellac, wax, or toner. Invisible repairs result from restraint, good light, and systematic, gentle surface leveling.
When finish is tired but intact, clean thoroughly, abrade lightly, and apply a compatible topcoat. Blend scratches with wax sticks and markers. Avoid heavy stripping unless necessary; thin refresh layers preserve patina, reduce fumes, and keep original character visible through subtle, protective sheen.
