Mid way through the initial regulation of Blüthner No.83988. Here I’m doing a rough adjustment of the “setoff”, on the work bench.

Re-fitting the keys to the keyframe. It’s very important to make sure the keys move properly, so each bushing will be eased or tightened to ensure frictionless movement, but without any slack. It’s a fine balance…!

Hammer No.1 prepared to be fitted to Blüthner No.83988. The hammer has been “spliced”, which is the name given to the process of cutting a chamfer into two of the edges of the bass hammers. The reason for this will become clear in later pictures…

First stage of bleaching the ivory key tops. The keys go through another round of bleaching before being fine sanded and buffed to finish.

Part of the Blüthner “Patent” action – known as an “Abstract”. Seen here having new cushions fitted.
