When legs of an ordinary table become loose and unsteady they may be easily repaired as shown in the sketch.
Ill: A Piece of Wire Bent around the Leg of a Table will Make It Rigid
Nails do not hold well in such places and glue will not stand much washing. The method of making the repair is to drill %-in. holes through the rails on each side of the leg and insert pieces of galvanized wire of a size to fit the holes. After the wire is inserted, the ends are bent over. The illustration clearly shows the repair.-Contributed by Edwin C. Wright, Newport, Ky.
