MkI Damper felts not making contact after storage...

[siderealxxx]

Hi, my MkI (1974) Rhodes has been in storage for about 3 years (unfortunately).

I now have space for it again and it mostly seems ok except that about 50% of the damper felts are not muting the tines. They do have grooves worn into them so I guess this is the problem?

I could bend the felts further to make contact with the tines but I might be pushing them too far. And I'm assuming the shims or anything like that isn't the issue (it was fine before).

Do I need to re-felt the dampers completely? Or at least on the problematic notes?

Thanks in advance!

Close up photos would help to determine the issue.
