I had a very loyal client came to me with an old desk(c18) that was too big for its intended position in a bedroom.
“Can it be made smaller by 8″ in both directions” was the request.
So all the joints were sprung and new mortice and tenons cut. New drawer back spliced in and a good waxing to the base.
The top was split but whole,so a new moulding to match the two existing sides was cut in and the top repaired and clamped for a few days.
A good polishing and you would never know it wasn’t made to this size in the first place.
