[CAUT] Lacquering Steinway Hammers

[David Love]

That's interesting then.  It suggests that the lacquer that I am using
should be diluted to 7:1 (24%) to achieve the 3% by weight that Steinway
uses.  The next issue is whether or not the solids content is the only
factor in determining what makes the felt more dense.  A 7:1 solution of
the lacquer I use doesn't really do the job without multiple, and I mean
multiple, applications.

I asked Eric that precise question. He was very clear that it was
weight,
not volume. I suspect they take lacquer that has already been formulated
in
the factory: IOW, it's not "off the shelf." I know they do take it
direct
from the factory floor (walk over and get some). I suspect Steinway buys
it
at higher concentration. Or maybe they mix their own.
