Hi Everyone!

Yesterday afternoon I worked on a Steinway L with teflon action centers. =
 First time a key was hit, it sounded arthritic with a noticeable =
"crick!" but on subsequent blows within the next few seconds, there were =
no "extramusical" sounds.  Furthermore, there was considerable =
resistance but only at the first blow.  Give the key a break of less =
than 15 seconds, and it started all over again as if it hadn't been =
played at all.=20

This problem was widespread, and seemed to be pretty evenly distributed =
throughout the piano.  My questions are:  What causes this?  What can be =
done to correct it?

Thank you --
