hammer hardener

[KeyKat88 at aol.com]

Greetings Dave,

                     I Would think this is a plastic keytop? Can I use any 
plastic keytop? Do all keytops have basically the same plastic composition? My 
guess is that they're all "close enough for government work".

Thanks

In this case I would probably use one or two drops of keytop/acetone solution 
fairly dilute (like thin non-fat milk color).  One keytop to 8 – 10 oz’s of 
acetone depending on the thickness of the key top.  Dispense it from a fine 
tipped hypo oiler in the smallest quantity you can.  Mix in a separate jar and 
put only about 1/16” of liquid into a 2oz hypo oiler which will allow you to 
control the flow rate much more easily (Pianotek sells them).  Let dry 15 
minutes and bang the hammer on the string a few times to break up the crust.   Don’t 
saturate the hammer, all you want is a little edge at the strike point.

        Well, to continue the "Lady with the Samick" saga there are 2 hammers 
that the ironing and pounding didnt bring up the tone 'bright' enough for 
her. So now I am looking at hammer hardner, I hate to use the acetone on only 
two, and I never used it before (never ran into this peroblem before) 

         What about the Schaff FORD hammer hardner. Is it any good? How about 
the brite tone? I bet the Brite tone is acetone. BTW Where does one obtain 
acetone. My first mind's idea is to buy a bottle as nail polish remover.
