For a vertical piano you get a lot of bang for your buck by reducing spring tensions. Often they are set way too high. Try an octave of damper springs, C4 to C5. Experiment with reducing tension until you get just a little more than what you need to dampen. You'll be amazed at the difference. Similarly, it's not hard to experiment with the hammer tension. The jack spring tension also plays a very big role and it isn't quite as easy to reduce. I've thought about sticking a screwdriver in to compress the lower 2 coils and adding a drop of CA, but haven't given it a try yet.

The owner and 8-year-old daughter both report the touch is too heavy. When I tried the piano, it was hard to play pp passages without notes dropping out here and there and, yes, it felt heavy. There is a card on one side showing the regulation specs. Notes 1 - 34 have 56g (DW) and 35 - 88 have 54g. I found that most of the keys had four leads behind the balance rail (half leads, two on each side). The few keys I checked, with the wippen raised, the lead weights seemed to be balancing the front weight of each key (see two photos below showing both sides of C4). All of the dampers are timed very early (dampers move after a couple of mm hammer travel). My question is, what would be the most technicianly way of reducing touchweight? Anything I need to know about this particular piano? -------------- next part -------------- An HTML attachment was scrubbed...
