[CAUT] Getting lacquer out of hammers - follow up

Hello, all

Some months ago I posted an inquiry about rescuing over-lacquered 
hammers by rinsing out the lacquer and starting all over. The piano is a 
New York Steinway D that has been one of our primary performance pianos 
- until we put a set of the pre-lacquered Steinway hammers that they 
ship these days. The voicing never went well, and the piano was 
relegated to jazz and pop combo performances and occasional 
accompaniment use all of last year. Before those old hammers wore out, 
this piano was first choice for recitals of many students and some 
faculty pianists (solo and accompaniment) and was preferred as the solo 
instrument with orchestra (we also have a Hamburg D and an older New York D)

After the end of classes, Margie Williams (the other technician here, 
who doesn't subscribe to lists) followed some of the suggestions we got 
from this list and subjected the hammers to several successive rinses, 
following suggestions made by Fred Sturm and Horace Greely. She used 
both lacquer thinner and acetone rinses, since it turns out that what 
Steinway puts in those hammers really is not lacquer but some sort of  
quick-setting plastic concoction. Margie and I collaborate on the voicing.

The results so far have been very good. The hammers came to life with a 
relatively light lacquering after the rinse - and are producing a much 
bigger and richer sound than they ever did before, even in the treble - 
which never produced much sound with those pre-lacquered (or 
pre-plasticked?) hammers. There are no classes or performances now, so 
we are letting selected students (who are ambitious enough to come 
practice in the summer) play this piano while we work to refine the 
voicing. So far the response has been positive. There is a good chance 
that by the time performance season starts the piano will approximate 
its old self with these new hammers. We'll see...

Many thanks to Fred and Horace and to all who responded. And, after this 
experience, I am staying away from those pre-whatevered hammers.
