Not as extensive as the last major repairs, but the center point for the legs of my wooden office chair had cracked very badly, making the whole thing sag on that side and tilting the seat. Took it apart yesterday evening, glued and clamped overnight, and reassembled this morning. So far, so good -- but I have ordered a new truck and base assembly.
The chair is at least twenty years old, built from a flat-pack kit bought at a home-improvement store. They don't appear to sell them any more. It's overdue to be sanded down and refinished.
Update, 24 hours later: glue bond broke. Not surprised. Maybe a little dowel action while I wait for the replacement to arrive.
