[pianotech] Chickering damper blocks

[Delwin D Fandrich]

Yes, it was me. (I've been off in a land were not all of the internet
features work most of the time when this first came up or I'd have commented
on it then. I can read the things that come in to pianotech but can't reply
to them.)

 

It was my first lesson in figuring out just how dampers work. And it led to
a brief study of "auxiliary mass absorbers" generally. Once you understand
how these things work you understand why so many of the modern
ultra-lightweight systems simply don't work no matter how much spring
pressure manufacturers unwisely (ignorantly?) put on them.

Hi, Ron 

Obviously you didn't hear Del talking about the need for both spring 
tension and mass to get good damping. The metal gives the mass, as he 
found out when he replaced a set of those metal damper heads with wood. 

Even though my life has become a series of Senior Moments, I'm 98.5% sure it

was Del who said this.

Regards, 
Susan

Wim, 
And what do you suppose was the reason for them? quiz for the day?<G>

Chickering did a long running set of experiments on the effects of
psychotropics on piano design. Different substances produced different
designs, and he eventually tried every combination of everything available.
These dampers, I believe were the result of the chlorpromazine/dark
chocolate experiment.
