Hi Sarah, Baldwin Hamiltons from that era (at least the ones I have seen) place positive pressure on the whippen. This means the jack spring has to be much stronger--but it also means there is never lost motion. A poor trade off imho, as when the instrument ages repetition gets flakey. The butt "leather" was Doe skin--then a modern mirical material called "corfam" which unfortunately got hard and clicked. Today many makers use "escane" which seems to have all the good features of doe skin--without killing bambies. Most people would focus on the jack flange reacting to humidity change causing poor repetition...but I think the wippen flange may be the culprit. >... which was once exactly the problem with my little >Hamilton. It was aggrivated by higher humidity. As I >recall, the Hamiton butt leather isn't really leather >but is some synthetic stuph. Perhaps it expands >somewhat with humidity??? Anyway, the cure was to add >a wink more lost motion, at least on *my* piano. ===== Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.P.T. 3004 Grant Rd, Regina, SK, S4S 5G7 Tuner for the Saskatchewan Centre of the Arts http://us.geocities.com/drpt1948/ __________________________________ Do you Yahoo!?
