Dearest Pianoexpert, first of all, HAPPY FERRAGOSTO from me, who for the sake of the country has remained at work... what a shame!!
Listen, seeing a Bosendorfer mod 2.00 1986 piano action online, I noticed that the repetition lever carries a screw where the relative repetition spring is attached; what is it for? Studying and observing it, I said to myself, between me and my other self, could it perhaps be to better load said spring, in a let's say "micrometric" way?
Instead of loading and unloading the springs with the appropriate hook wire, that screw allows us to load or unload the spring itself minimally. Compliments for the careful observation and Happy Ferragosto
On this occasion, I wish everyone happy holidays and a now past happy Ferragosto. Unfortunately, the forum has emptied out this month; in any case, post, post, post !!!
