Jack button punching compression

[John Ross]

I'd be tempted to find a different punching.
There appears to be at least 3 thicknesses available.
Even after compressing, I don't think it will stay, unless you possibly dampen them, or something.

  Howdy,

  I'm replacing the jacks in some Thayer wippens.  The replacements have really big, fluffy jack button punchings--which put the jack position too far forward and if I bend the spoon backward to get the jack back far enough, there isn't enough tension on the spring that's held by the loop on the jack.  (Follow me?).   Instead of trying to compress the questionable punchings on the jacks, I think it's easier to compress a set of replacement punchings that I have which look less wild than those on the replacement jacks, but still need compressing.  Then I'll simply replace the original poofy ones.  The punchings are on my bench, under a cutting board that is weighted down.  

  Here's the question--(drum roll):

  How long should I leave the punchings under the weight?

  This piano belongs to a friend and it will be a good project for her to replace the punchings.  Hmm, I'll have to think of a few other little jobs for her to do...

  Thanks,
