[CAUT] agraffes

[Wigent, Donald E, Jr]

Hi Rick and every one Don Wigent hear.  Isn't all this business about
removing and reinstallation of agraffs a lot of un necessary work unless
you have problems?  Perhaps we are afraid of problems with noise after
we restring.  In my limited rebuilding experience (maybe 6 pianos or so)
I haven't had much trouble with agraffs. I have on occasionally seen
agraffs  become jumpy and pinggy.  however I have seen
-----Original Message-----n several spirious sounds from capo bars. Most
of those have disappeared with resurfacing of the bar. Can you shine up
the agraffs without removal.  Maybe I am not conscientious enough.

Hi Karen


If there is a problem with getting the action regulation good because 
the height difference then you have a nice problem in front of you.  You

cant add or subtract washers because then you will alter the alignment 
of the agraffe when tight.  Milling t	he underside of the agraffe
would 
essentially do the same thing... tho you could do this AND subtract 
washers to get your result.  Milling the plate itself would work I 
suppose, but any milling to do this would be really fun to achieve a 
perfect result with.

You could always replace agraffes as part of a restringing job... have 
enough new agraffes on hand so that you can choose which ones align when

tight and are at the same time at a more uniform height. 


Cheers

    Willem,
    I understand the usage of washers for aligning agraffes
    perpendicular to the
    the strings; in this case there are visible differences in heights.
I'm
    thinking of removing some of the washers and adding to others so the
    heights
    are within a few thousandths of an inch.
