Following the useful advice on this forum, I've now got my 1 yr old Kawai RX3 holding its tune - all except two notes (B4 and Bb4). I'm sharpening with a definite movement of the pin, and then spending a good 2-3 minutes bringing a string down, playing it regularly with the odd test note. I can then get the note perfectly in unison.

However, if I play for 10 minutes, one of the strings has slipped. If I set it slightly sharp by 1 or 2 cents, it'll hold there perfectly for days it seems - but if I set it perfectly in unison, then it slips. It also seems that tuning the left string will often put out the right hand string and vice versa. The two notes also seem to have decided to influence each other...

Yes - I've probably been too particular since I've owned the piano, and tuned it much more than I should have - but I have been very careful not to "flagpole" the pin, and I'd have thought it would be pretty difficult to totally ruin the pin seating in a one year old piano.

Is it worth considering a quick tap to try and seat the offending pins a little more? Anything else anyone can suggest?

definite ? you mean fast ? I do not "sharpen" I tune "from below" , with enough overpull to put the tuning pin back in stressed posture.

This is not much felt on Kawai but You may try to add something to the tuning pin itself in order to it to have more grip.

Raising very slowly the pitch allow to move all the wood fiber that can move, once oriented they will lock the tuning pin better.

if nothing works you could tap the pins but on a one year old piano ?

You must feel the tuning pin grip, counting on a natural braking without helping the pin torque is not enough. THe wire help the pin but the pin must be active
But I suppose you understood this

It sounds like you're not sure if the problem is the piano or your tuning technique. You could hire a tuner to see if s/he has any problem with those notes before you attempt any interventions.

My take is that 2-3 minutes on one or two tuning pins is an awful lot, and it's possible that you're heating up the string a little working it up and down, and that's not going to lead to a stable unison. Working the pin back and forth is also putting a good deal of wear on the pinblock. Try to spend a lot less time on each string.

Since this piano is only one year old, you need to find out if you are required to have a professional tuner-tech work on it. Or, if you might have already voided the warranty by working on it yourself.

Hi Olek,

By "definite", I mean that I'm sure the pin is moving; however, I understand your point about tuning from below. Sometimes I forget this.

I wasn't quite sure though what you meant in the last paragraph about 'natural braking'...?
