Action adjustment

Post by markymark »

I bought a Yamaha P121. Since having it and played other pianos, I've come to realise that my piano is not as perfect as I though.

> Keys are a bit on the heavy side. The retailer said that they would "loosen up" with use but after a year, this hasn't really happened.

> Piano is quite loud and there is little distinction between the sound when using the soft pedal and when playing it without.

We had to move the piano a couple of weeks ago to lay a new carpet so before I call the tuner to retune the piano ( :roll:), is there anything else I can get him to do while he is working at the piano.

Touch
He should measure the friction and then to reduce it by
  • He can Teflon the jacks and heals
    He can protech the capstans, bat pins and balance pins
    He can ease the keys
if at the end of the day the action is still to heavy he can alter the action - key ratio

last resort alter the key weight

The last two need to be done be a good tech and will cost the first takes about 1.5 hours


Tone
He can tone it down

Check centres and ease keys are important and i think this is where the problem is. I probably wouldnt go down the route of changing key weights, this is more with fine grand regulating and very rare to do unless new heavier/lighter hammers have been used.
Teflon the butt leathers is also recommended. Also the dammper spoons need looking at, they could be lifting too early ( well check all regulation in fact).

My money's on dampers lifting too early and spring tension too strong.

Thanks for the information. As Barrie said, the piano probably wasn't prepped from when it left the factory! All I know is that I'm having to put too much effort into playing the instrument and that it is sounding too loud even when I am trying to play "pianissimo"!
