List I have made a couple of piano keys as a last resort to repairng the broken originals. I used yellow poplar mostly because of availability. I understand sugar pine, basswood can be used (maybe check with a manufacturer). I took all the keys around the broken one out and developed the pattern for the new one with their profiles. Remember to mark which side of the line to cut along. The first attempt was a disaster. The second, I made the key slightly oversize in width. This allowed me to custom trim when I got back to the piano. Pin hole and key button placement was easy, using the neighboring keys as guides. Adjustments side to side were done by trimming the excess width of the key during the final fitting at the piano. With all sides trimmed to fit, the key top was glued on and the required regulating done. I hope this post isn't too late to help. Paul Chick rpt Plainview MN
