Whippen cushion

[Isaac OLEG]

Ric,

I changed a green too soft cloth (Renner pure wool)10 days ago on a
Schwander type action. Used white 3 mm action cloth from Renner, with
an amazing improvement.

Time spend around 4-5 hours (because old felts was very tightly glued)

Best

Isaac

Yes.. but there are many different materials used on different
whippens.
In particular Petrof used (perhaps they still do) a green strip of
relatively soft felt that developes this deep cup with use. You can
manually hold the whippen down while pressing on the key and
watch/feel
the capstan press easily into the felt.  Same stuff on their uprights
I
think.  I've always thought Petrof actions felt very mushy and not
very
precise.  Hard to get into a stable regulation.  Anyways... just on a
hunch... I'd like to try using different kinds of material there to
see
what I like... and an appropriatly pressed Wurzen is on my list.

Well, I sure as hell agree that I dont like it when whippen cushions
are
too soft.  On the other hand.. too hard can get noisy.

No, not really... just musing.
