The strings will be stretched between hooded steel fasteners called hitch pins, attached to the back end of the plate and steel tuning pins. The tuning pins will be anchored in the pinblock, a heavy block of wood behind the keyboard. 240 small holes must be drilled into the plate. Holes are also drilled for the bolts that will attach the plate to the rim.

Wearing tape around his fingers to protect them from being cut by the piano wire, the stringer puts on the 201 silver-colored treble strings first-three for each treble note.

Each tuning pin has a rounded end, with a hole for the string to pass through and a pointed end. The piano stringer hammers the pointed ends of the tuning pins through the holes in the plate into holes in the pin block. He has to pound the pins very hard, forcing them deep into the pin block so they will fit tightly. It is a very noisy job! While this is taking place the action of the piano is being built.
