softening wippen cushions

[Isaac OLEG]

Hello

Steaming works for 1 year but not really more, from what I've seen so
it's up to you...

Cupping will be back , be sure of that.
per , but you need to have special cauls made to obtain enough
tension. If a mushy felt is on the whippen heel, friction increase
dramatically.

Fine polishing of the capstans and fine lubrication helps a lot too.

Regards.
