The other day, while moving the table into the southeast chamber, the stretcher came loose from the legs. Both insert nuts at each end of the stretcher had pulled out from the wood. I got two larger connectors (with significantly larger insert nuts), tapped the nuts in along with some wood glue, and after the glue set up, drew the legs and stretcher back together. A once-over with some lemon oil and the table was good to go.
Above left: One of the original connectors and its replacement. Above right: I chamfered the face holes on each leg to accommodate the larger connector heads.
Above: New connectors in place and ready for service again.
Above: When combined with a hardwood stool, my trestle table makes for a highly efficient work area that's downright medieval in its austerity! ;-)
