Are you sure that the jack is not hitting the underside of the hammer
flange?  Sometimes if the parts are mismatched and you have a high
leverage system with a low leverage regulation (deep dip and excess jack
travel), the jack can come all the up underneath and strike the hammer
flange.

>>I’m working on a Steinway D here and it has some clicks in it that are

>>stubbornly resisting my best efforts to eliminate them.  This is a
1970 
>>vintage piano that has some level of action rebuild done in 1993
(before 
>>my time).  Some of this work wasn’t done particularly well, so over 
>>semester break I put new Renner shanks & flanges and Ronsen hammers on

>>it.  It turned out very nice, but there are five notes in the low
treble 
>>that click when played.  It initially sounded like the click happens
at 
>>hammer impact, but I think it might be triggered by the end of 
>>keystroke.  The click seems to be in the wippen, since when I pull the

>>action and lift the hammer out of the way, I still get a click, but if
I 
>>hold the wippen up and strike the key, I get no click.  It doesn’t
appear 
>>to be jack top hitting anything, but I can’t find the source of the 
>>noise.  This is particularly frustrating because I’m usually pretty
good 
>>at diagnosing this sort of thing.  I’m getting this piano ready for a 
>>concert this Friday, so I’m beginning to be a little anxious.  Any 
>>experience, ideas, or wild speculations out there?
