How can I loosen glued chair joints that are still tight so that I can reglue other joints that have loosened?
If the joints are stubborn, lay the chair on its side and brush the joints with warm vinegar. Or put the vinegar in a small, clean oilcan and apply it to just the right spot. It should dissolve the glue without damaging the finish. (Tip: Yellow carpenter’s glue is best for regluing a chair.)
