Steinway A #280251 Bridge work

After the proper thickness is determined, the bridge tops are planed, and sanded smooth. The bridge pin hole locations are placed on the new top using the patterns made earlier. Then the holes are drilled, the top dyed black, and the bridge is notched. Finally the new pins are installed.

Steinway A 280251 Setting the bearing

Setting the bearing involves planing the tops of the new bridge caps to the correct thickness. The goal is to achieve proper overall down bearing as well as correct front and rear bearing. This is achieved by dry fitting the bridges to the soundboard, and dry fitting the soundboard into the piano. The plate is then installed at it's intended location, and a string is used to determint the new string line. A small kurf is cut in the bridge at numerous locations at the desired height and angle. These notches are then used as a guide to plane the entire bridge top to the correct thickness and angle.
