    What type of protocol do you use to keep a concert instrument playing at its best? I have responsibility for 2 such instruments and wanted to check to be sure I was doing what is needed to keep them performing at their top for the years to come. Things like maintenance schedules, when to replace hammers, when to restring and especially things that your do that may not be obvious but make a difference. 

    Thanks.

    Great question Rex. A few thoughts to get things rolling...
    Concert instruments, as far as when does it need major work/parts replacing/strings, or more of a comprehensive refurbinshing really depends on each particular situation, the dynamics of the piano faculty, staff, etc-who you are trying to "please/keep happy"-and of course FUNDING. I have found that usually you (and/or some of the faculty, etc) will just KNOW that things must be done. If it starts breaking strings then it is time to begin planning ahead, and planning on either a full restring (which of course may be the time for a new block, bridgework, etc) 
    If it becomes difficult to get the full well rounded, etc etc-tone you are wanting/needing out of the current hammers, then it's decision time on at least trying to fund new hammers/shanks/flanges, whipps, etc (if at all possible)

    Regular maintenance (between semesters, or when possible):

    -stay on top of the regulation
    -lubrication such as key bushings (& deal with loose ones ASAP)
    -Don't let hammer grooves get too deep or out of hand-but do NOT file too often. Very fine sandpaper strips works incredibly well for maintaining this. (Another topic here!)
    -inspect lid hinges & casters/legs on a regular basis
    -keep the voicing as even & nice as you can on a weekly/monthy basis but again do not OVER do it. 

    These are some HIGHLIGHTS-let the chiming in & discussions begin.

    I did a class called "Getting it 'Concert Ready' and Keeping It That Way" a few years back. Later I morphed it into "Laying a Grand Foundation." I'll attach the handouts, as they address your question pretty well - not parts replacement protocol, but the prepping and ongoing maintenance aspects.

    Fred,
    Those were enjoyable to read. Thanks for sharing. 
    I have never worked with lanolin, might make an interesting topic for discussion.

    I have changed my mind about lanolin - at least using it in its raw form. I discovered that it caused the felt to gum up sandpaper when filing later, very badly. Lanolin oil might be fine, but I haven't tried it. 

    I have substituted different techniques in needling, so that I haven't found it necessary to use any additives for a few years: 
    • always have the hammers in a situation where I can stand and press the needles into the felt, using body weight. 
    • an insertion pattern where the first insertion starts just above the bulge of the hammer, and is parallel to the hammer felt (it is maybe 2 - 3 mm from the outer surface). That opens the felt for the next insertion, that is parallel to the first. Hence, the amount of force required to get the needles into the felt is reduced, and it is possible to open up the felt deeply without some kind of extreme measure. (For more details, read my article in the "Taking the Upright Seriously" series that talks about needling.

    Thank you for the information, especially Fred. I realized after asking the question that what I really was looking for was what Fred provided. Will take some time to look it over and see where I need to adjust. 
    Once again, thank you for your responses.

    YES! Was hoping Fred would chime in. 
    I LOVE his key bushing & frictrion "protocol". We were going through key bushings WAY too fast. Not so much our concert pianos but piano profs, practice pianos, etc etc. 

    Rex, out of curiosity, what are your two concert pianos? (If you don't mind sharing). We tend to sort of assume Steinway Ds but...
