[pianotech] Best way to change touch on Yamaha Grand

[Barbara Richmond]

Or recycled ideas. :-) One thing I didn't mention, is you can adjust the amount of change by where exactly you cut the punching--making the cut exactly half way though at the balance hole point, or a little further back, etc. 

I have a blast working on actions that people complain about being too heavy. I like doing the detective work and solving the puzzle--there have been some interesting ones!

Hi Denise, 

The half punching is used at the balance rail, the conical (Crescendo) punchings are front rail punchings--or maybe I'm not understanding what you are referring to. 

In this case, maybe quick and dirty is a little overstated. But it is a lot faster (and easier to un-do) than moving capstans or knuckles or reducing the hammer weight. I've used this method on pianos where the touch was just a little heavy. 

An added bonus is that leveling keys on the pianos with the glued on punchings is a snap--there is no lifting of the cloth punching when adding or subtracting paper punchings, since the punching lifts with the key. 

Best,

Thanks Barbara, 


They didn't teach any "quick and dirty" at school, so I'm glad I have all of you to help out with this! Awesome. 


Have you ever used those punchings that are conical? Seems they operate on the same principle. I've never seen them or any glued half punchings in pianos to date. But then the year is still new. . . . . 


Cheers,
