Stieff Plate Removal and Veneer repairs

Disassembly Complete
Yesterday, disassembly came to an end, as I was down to the soundboard! Ryan helped me remove the plate. We used the shop crane to good advantage. I'm glad we had it! Lesson learned: bind points are at the front of the piano, not at the back. Thus, it is important to lift primarily at the front. It wasn't a problem as we went slowly and monitored progress well.

Piano vintage confirmed:

While the eBay listing for this piano suggested it was made in 1905, the serial number is only three different from my own piano, which had been dated to 1911 by the prior owner. Upon the removal of the plate we found the 100 year old chalk marks on the back which clearly identify this piano as 1911. End of story.

Veneer Repair Begins
My hypothesis is that the piano was stored on its side in a damp location at one time. There is evidence of mold on the soundboard and bridges of the piano. The veneer suffered buckling and separation on the left side. Repair to the buckled veneer is to be as follows:

  1. Rout 1/8" channel through the buckled veneer at its peak to relieve the buckle.
  2. Re-glue the veneer
  3. Fill the routed channel

The inside veneer was separated at the top. It was re-glued using Titebond glue applied with a veterinary syringe.
