Sitka spruce from Washington State is the beginning of a new Soundboard. The wood is quarter sawn, straight grained and clear of any defects. 15 pieces are selected, grain oriantation determined, and cut to length needed. I edge glue 3-4 pieces together, then thickness plane them to the desired thickness. Then these 4 pieces are glued together.

Below are pictures of my most recent rebuild start. Even though I haven't added pictures recently, I have been very busy. This piano will get a total restoration with refinishing. The first picture shows the old pin block, bridges and soundboard. On the soundboard are the rough cut ribs which are the start of making a new soundboard. These will be hand fitted to the piano rim for a tight precise fit. The second picture shows the piano body with the soundboard and pinblock removed. More will follow in the coming weeks as work progresses. In the mean time parts need to be ordered.This is expected to be about a 12 month process.

It has been 6 months since I last posted here. It has been a very busy 6 months with 4 major rebuilds happening at once. I am grateful for the full schedule, but am glad to be finishing up the second of these projects. After the bridges were glue to the soundboard, the board was finished and installed. Following that the piano was sent to the refinisher.

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.

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.

Installing a new pinblock requires the rebuilder to mate the wooden pinblock perfectly to the cast iron plate. I a Steinway it also needs to be perfectly fit toe the case, with ends tight and the front mated with the stretcher. The pinblock must also be the correct thickness and also located correctly both side to side and front and back. The pictures below tell some of the story.
