Hi Jeff, I'd be more than a little hesitant to do a partial restring one week, and have the piano in a performance situation the next. If I were you, I'd wait until summer. It's possible to get reasonable stability that fast, but not at a "concert level," IMO. I've done a complete restring on a concert instrument, and had it in performance a month later, and that was awfully tight. There were issues, to put it diplomatically. Not fatal, but not exactly the sort of thing that burnishes one's reputation. I'd also advise replacement of bridge pins, not just CA. The pins themselves develop grooves, which generate string noise in various ways. And the bridge top itself is fairly likely to have grooves where the strings cross, especially if anyone has been tapping down strings over the past 30 years. If I am doing as much as restringing and dressing the capo, I'd just as soon get all the terminations as close to optimum as possible. Meaning pull pins, surface and renotch, replace with new pins - sizing the holes. Adds a few more hours, but worth it, IMO. To get pitch stability as fast as possible, my own procedure is: 1) Get moderate tension on strings 2) Clean up coils 3) Space strings to hammers (using their current positions as a guide, evening out where appropriate) - tension is well below pitch, strings slide easily along capo without "planing off" the lubricant I have applied and shaving up little bits of buzzing-source metal 4) Pull to pitch 5) Pull to plus 25 cents 6) Work strings back of bridge: massage with brass tool, creating positive bends on duplex and against bridge pins. 7) Pull to plus 25 cents 8) Work strings front of bridge: massage with brass tool where possible, string hook where needed, to create positive bends at capo and aliquot humps 9) One more tuning at plus 25 cents. Leave for at least a couple days 10) Massage strings vigorously. Level strings using string level. Tune to pitch. Tune entire piano.
