[CAUT] tone building for impatient pianists

[David Love]

I should add that the dilution you use will depend on the solids content of
the lacquer you are using.  I'm using MacLac G23 clear gloss which is a high
solids lacquer.

Middle down won't have any effect.  The lacquer needs to creep up underneath
and even onto the crown firming up the felt between the strike point and the
tip of the molding.  4:1 is too strong, in my view.  2:1 as someone
suggested is way too strong if you are letting it go to the crown.  About
9:1 is all I use and apply it to the shoulders (each side) letting it creep
all the way to the crown.  Since you've already done the 4:1 on the
shoulders I would make a solution of 9:1 and apply it directly over the
crown letting it saturate to the tip of the molding.  If you want to avoid a
lot of crustiness in the mid tenor down through the bichords than using a
hypo oiler with a fine needle put a couple of drops of pure acetone right on
the strike point immediately after the lacquer application.   If that's not
enough then a second application of 9:1 should be enough.  The second
application will definitely require you to needle out the pings throughout
the piano but it will be fine.  

 

Btw, I assume you mean 4:1 acetone:lacquer not the other way around.  

 

 


I'm having trouble with my Ronsen Wurzens on my Baldwin D, but am scared to
start putting stuff on the crown.  I've used 4:1 Laquer/Acetone a bunch on
the shoulders (middle down to the bottom)  with no improvement on power.
The false beats are gone and the sustain is great after installing Wapin on
it, but I fear a lot of the problem may be a tired soundboard.  If I were to
add a 5:1 or 4 or 3:1 on the crown, or nearly on the crown, am I endangering
the situation? Or, would you suggest putting any straight on the crown?  The
mezzo-forte on down to very ppp or pppp...the piano is lovely and the notes
sing and carry to the back of the recital hall(that seats 750), but there's
just no power. 

What do you, or any of you suggest my next play??? 

Thanks 

Paul
