<html> <body> Hi Phil & Horace,                              Assuming you have good sound board crown and correct bearing.           Once the older CF111's start to get Capo bar grooves the sustain tends to drop quite a bit in this register.  Drop the tension on two notes so you can thread a strip of Emery cloth between the Capo and strings, shoe shine the capo bar to remove the grooves, pull back up to tension and check the sustain again. I think you will find an improvement. Lift the strings so there is a lower amount of forward duplex bleed,  tap the bridge pins to make sure they are secure, and the strings are well seated.  This will improve sustain. Make sure that all perimeter plate bolts are secure.   Hammer shape??????   Hammer fitting????  Glide bolts are critical on this piano for optimum sustain and power. What is the hammer flange centre pinning Like? 4 gms of friction is optimum.  What is the let off and drop Like? The new CF111 hammers are made from Wurzen Felt and will produce much better sustain.   A World of difference from the old style hammers. Should give you some food for thought.

Also assuming that these are stock CFIII hammers, they really do not like much in the way of liquids; and respond much better to quality shaping and judicious needlework to develop tone.  (The techniques are much more like working on Bechstein or Bluthner than a North American instrument.  Various folks have written about approaches.)  If, however, they have been over needled across the crown (a growing problem), either be pleased that you can pass this work back to someone else or try to sell a new set of hammers.  Since you said "CFIII" and not "CFIIIs", this sounds like an older instrument which might well be ready for a number of things. I'd be interested in what you find with some further diagnostics. Best.

There is good tone, with no sustain. Is there something I can do for these few notes to blend them in better? The tech that normally has this piano in his possession does not like liquids..and I'm not sure this is really a hammer problem since there is good tone, but no sustain. Any ideas?
