The pin block in a grand piano is obviously an important component to both the stability of tone and structural integrity of the instrument. Logically, care must be taken during the manufacturing and re-manufacturing process to ensure a secure and tight fit between the pin block and the cast iron plate. Recently we have come across a number of pianos where care was NOT taken during the factory manufacturing process. We have begun/completed work on a number of Young Chang grand pianos where the fit between the plate and the pin block quite frankly was almost nonexistent as you can see in the photos below. Young Chang utilizes a very fine quality pinblock, so the bad fit is rather unfortunate.
To repair the gap between the plate and block, we utilize an advanced synthetic wood. This compound is dye-able, sand-able and is formulated to act and feel as much like wood as possible. It truly is the best solution we have discovered when completing repairs such as this. We added this compound to the gap. This particular repair took several softball sized balls of the compound to fully fill the large gap. The amount that we had to use was actually rather shocking to us. The alignment was checked repeatedly and the compound was sanded and adjusted to ensure a tight fit. After the alignment was snug, it was coated with a protective coating for additional durability and smoothness. After this process was completed, we then reinstalled the pinblock, re-seated the plate, re-strung the piano and re-installed any other parts that needed to be removed to reach the Young Chang pinblock.
We wrote an article that goes into more detail on how we repaired these instruments. To read the blog post, click here.
