Hi Danilo, Replacement of parts is always the ideal, problem is that many of our customers cannot afford the cost of rebuilding the action. Still we, as piano tuners, are required to make the instrument we are working on play to the best of its ability without major cost. Over the fourty odd years that I have been 'fiddling' with pianos I have found that many of the so called 'good' piano tuners don't reface hammers, don't regulate actions and don't tune to pitch. So forget about trying to rebuild everything or just tune it, work for the customer and improve the piano as far as you can. Tell your customer that there is much more that can be done and you would advise it (in some instances) but the cost may be more than the piano is worth. Re Action. You will find that after you have all the hammers rising firmly (but not rushing) that the repetition lever is still below the hight of the jack. Your drop screw may be too low stopping the repetition lever going up high enough or (and more likely) the repetition regulating screw at the hammer end of the re[etition lever requires adjusting to allow the top of the jack to be just below the top of the repetition lever. Remember when you make one adjustment another goes out, you rectify that and another goes out etc etc. Eventually the errors created are small enough to ignore and you have finished. Remember price. a rough job is $100 a reasonable job is $300 a good job is $800 a fantastic job is $10,000. Your call.

I thought the very same, that since these parts need to be replaced, I can use whats left of them to educate myself further. The aim, of course, is to make them perform better. Born out of necessity, actually, a recording session in the middle of the night, not the best time to call a technician! But that was two years ago, and a lot of "seeing and feeling" since then, as well as self-studying and asking technicians that I've met. Parts that need replacement will not respond ideally to being regulated, I guess. This is where the spring tension comes in. I did actually start working on them, and it was then that this problem arose. They are quite tense now, and it indeed causes some hammers to double-blow on the strings. And when I ease them up so that the hammer rises gently when released from check, the jack starts to not wanting to return under the knuckle properly. I was convinced it was due to the reduced weight of the hammers, but you've made me not so sure of that anymore. Knuckles need lubrication? (and replacement?) Spring needs to be cleaned perhaps? By the way, how would you diagnose that a spring needs to be replaced (unless broken of course)? Yes, a mentor would be very welcome, and excuse any language errors, english is not my native tongue. Very glad to hear about your background, Tony! Regards, Danilo ------------------------------------------------------------------------------ Smaka på vårens godbitar!
