Comments and questions on an earlier posting suggested interest in what was done with the left-over keys from a piano repurposing project.
As stated in that posting (https://www.hometalk.com/43336777/piano-repurposed-into-a-bookcase) the clients wished to have them repurposed into key racks for siblings. The purpose of this posting is to show the results and discuss some key points (pun intended) encountered in the process.
Most of my projects are one-of-a-kind. Doing seven sets at a time was a little tedious for me. I tried to mimic, but not replicate key racks I had seen on the internet.
Short version: The 88 key were divided into seven sets of 12 keys- 7 white, 5 ebony. The 12 keys were attached to a backer board along with three hooks to hang keys on and two hangers to hang the rack. Feel free to jump to the end of this posting.
Long version: After the keys were separated into sets, some white keys were missing or damaged. I was able to remove damaged ivories and selected good ones by placing them in boiling water. The ivories probably were attached with hide glue, but I reattached them with polyurethane glue so I was able to have six sets of seven white and five black keys and one set with no ivories.
With one of the sets of black and white keys, the color of the white keys varied so greatly. I painted them with a muslin latex enamel. Unexplainably the paint crackled on drying which gave them an aged look I decided to live with.
The set with no ivories was re-veneered with iron-on birch veneer tape. Over lapping edges were trimmed, sanded, and finished with satin urethane.
