Upright Wippen Rebuilding Questions- about glue for felts

[Isaac OLEG]

Hello,

I gived a try to fish glue for key end felts and grand dampers, and
have find it very easy to use, thin but not too much, plenty of time
to have the parts in place, it can be removed with warm water (but
more than usual hide glue).

Do some others have use it ?

Best Regards

Isaac OLEG
