The Blüthner Style-X is approaching the end of its first regulation. The next job will be to weigh the action to ensure an even touch weight.

After weighing, I will tune the piano once more before fitting the dampers. The next job will be to sit and play the piano for a few hours to get the action settled, and start work on toning the hammers.

As you can see in the picture, the key spacing isn’t correct at this stage – this is one of the things that will be addressed during the second (fine) regulation. The letters on the front of the key frame refer to different thicknesses of washer (which are used to adjust the height of the keys) on the balance rail – Blue, Green, Paper, and Telephone…!

Having re-bushed the keys, here I’m “easing” the bushes to ensure the keys move correctly, and without resistance.
