[CAUT] Lacquering Steinway Hammers

I think it's worth knowing whether or not different lacquers will
produce different results at similar dilution levels.  There is quite a
bit of difference between 12% and 26% solids if you are using a 3:1
dilution.  If Eric Schandall is correct in his report, then the solution
advocated by Steinway is a fairly light solution.  This might explain
why different people report using various dilution levels and seem to
achieve similar results.  Using a high solids lacquer with a 3:1
dilution may produce a hammer that has a much higher concentration of
lacquer than is desirable or that will develop well over time.  With all
the talk recently about "over lacquered hammers" and the wonders of
Wurzen, I think it's a microscope worth looking through.

  Come on now get your nose out ta da microscope maan. This is not all
that difficult & there are no magic lacquers it's jsut what's available
to them. If you've found straight nitro cellulose lacquer then thin it
and apply it until your familiar with the result. 
   I think Patrick said Wurdack. He's right. Its a high solids lacquer
designed to be sprayed hot at about 150 degress & has a distinct odor.
It takes many moons to really get hard ,just look at the the black
finishes coming out of the plant where the buutons hit the rim.
 Out here in Calif We have US cellulose  brand that most refinishers in
this region use & it works fine. 3 to 1 is a pretty stiff solution & I
usually use it as my intial dose of Stwy hammer lacquer but it depends
on the initial density I percieve inherent in the felt as they come out
of the box. I use it on Many different kinds of felt. Whats the solids?
I dont' know & don't really care as long as it makes the hammer stiffer.
I'd avoid a lacquer that had any varnish or other non lacquer type
additives.
 Use the ventilation all.
