Prior to the conversion of a Chicago piano factory to the manufacture of parts for trainer planes, Lorraine Avezzano operated this boring machine to prepare piano keyboards for further assembly. Today she uses the same machine to process connecting rods for trainer-plane motors. More than 1,000 of these rods pass through her hands each day. Gulbransen Company</div>
