Hello Pat,
The reason these hammers are covered with leather is
that when the hammer strikes the string it blocks and slides
a little this is the " let off ". It was thought then that the leather
would last longer.
If you press the key down very slowly you can easily see it
slide on the string. I have found that most of these pianos were
not and were not intended to be " loud " by today's standards.
Most of these actions were built by ether "Stein" or "Walther"
If I ever voiced these hammers up, I would treat the felt without
touching the leather or be prepared to replace the leather.
I wish you success
Jack Wyatt

Hello All: I have taken on the project of bringing a 1910 Ludwig Feigel 6'
grand back to playing condition. It is actually in very good condition
considering it's age, tuneable with a good soundboard and pinblock. It has
what I believe is a Viennese action, with leather covered hammers. I have no
idea as to how this would be regulated, or how to voice the hammers. The
soft leather gives the piano a very dull tone, so I hope to be able to
brighten them up. I don't know if the leather covering is original or not. I will
start by easing the keys, which are all tight on their balance pins. Where
to go from there?
Thanks for your help.
