[CAUT] profelt

[Porritt, David]

An anecdote from earlier this week.  I used the  Profelt on the key
bushings of a practice room M.  I used more than a couple of drops but
far from soaking.  I inserted cauls and let them set overnight.  In the
morning I noticed that I had missed inserting the caul on one front
bushing.  While all the other bushings were solid and improved, the key
without the caul had the bushings totally unglued.

I just talked with Bob at Pianotek and he said they soak the bushing
before installing the cauls.   Not 1 or 2 drops. 

It may be a way to use more product...;-]

 

Hmm, doesn't sound like a good plan to me. Maybe it works much of the
time, but if the solution dissolves some of the glue (if it is water
based like hide or aliphatic), it is likely to wick some into the felt
while it is sopping wet, and the wetness is slowed from drying by having
a caul next to it. Seems like it would also slow the process a lot. How
long would it take to dry?
