Hi Chris,
I had the same problem on a harpsichord I built in the seventies and just recently decided to restore and also try and quiet down the action.
I found that the cloth I used for the back rail and key end cloth were all as hard as rock.  What had happened was I originally glued them on and the glue soaked up enough throughout that nothing much left soft was left.  
The key I discovered, after talking to a couple knowledgable builders was to nail the cloth in place with very tiny brads - out of the way of where any jack bottoms would be.
And for the back rail cloth nailed where the back ends of the keys do not touch.
This made a huge difference.  I used a brad pusher to put the nails in with.
The nails I used were these:  https://www.aircraftspruce.com/catalog/wppages/nails.php <https://www.aircraftspruce.com/catalog/wppages/nails.php>
I found the 3/8” worked pretty well for me.
You can also use an air stapler with very tiny staples.
Good luck.  
Tom

Dear members,



I'm reviving an elder harpsichord. What still troubles me is the sound I
hear when the jack comes back down on the keyboard: there is a definite
"thunk" to be heard. They keys have felt on them but maybe the felt is too
old? Any ideas how to solve this. FYI there are screws on the bottom of the
jacks.



Greetings,



Chris.
