I hoped for great improvement in tone. While I got some, the piano still lacks power terribly. I am in the process of adding keytop/acetone which is giving some help but still not what I want. >> Greetings, I assume you used Steinway Hammers? If so, then the first thing needed in their preparation is to soak them, and I mean "soak" them in the proper lacquer/thinner mix. Use a squirt bottle until the whole hammer appears wet, (Steinway uses what they call 4:1, but if you are thinning the more usual refinishing lacquer, it will probably be closer to 6:1). Without the hardening solution infiltrating the inner core of the hammers, they will never project with the power you are looking for. Using acetone/keytop for this will be way too much, and if you are trying to work up hammers with keytops without the core being hardened, you will increase attack without increasing the tonal body of the sound.
