Voicing
« on: July 17, 2020, 12:52:15 AM »
I have replaced grommets hammers and dampers on my Mk11 project. I have one note (B4) that stands out as more bell like than the rest of the piano. I have moved the tine to different positions in relation to the pick up but it still is an anomaly in relation to the tines around it. What are the steps to try and get more even tone? Replace the tine? Learn to accept the imperfection?

I guess there are a few extra questions:
Is this tine at the break-point between hammer hardnesses? That might make it appear different by contrast.
Is the tine obviously from a different batch - colour of plating and other physical clues.
Usually lifting the tine tip above the pick-up nose makes some difference. Do you hear any difference?
You could try shortening it very slightly and using a slightly heavier spring weight.

Then move on to tine swapping until you find one that fits in.

I would try one simple test first...

If you have any spare hammer tips, replace the tip for the note in question with a softer tip to see how it changes.

If you do not have any spare tips, then remove the entire tine and tone bar for the note that sounds too bell like. (the 2 long screws w/springs)
Then, swap it with a tine to the LEFT (one with softer tips) that sounds good to you, just within a couple notes away. If the tine in question suddenly sounds better, then it means that likely you want to replace the hammer tip with a softer tip. If not, the tine may need replacing.

I really feel the tip hardness is the issue.

I moved the problem tine down a half step and the problem of too much chime sound moved with it.
I noticed the tuning spring was much further up the tine than the notes around it. Maybe it was cut short in the factory? 
I tuned it down a half step and swapped it with the tine 1/2 step below but that did not cure anything either.
I will order a new tine.

What happens to the problem tine if you move the spring? Obviously it will go out of tune, but what about the bell like sound?

I moved the problem tine down a 1/2 step and retuned reset the pickup distance. There was no change in the tone.
It does not look like the the tine was ever replaced.
