Ron N _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives But usually grand shanks are larger than 7/32", so the hole in the = hammer head will be too big. Maybe you can splice part of another grand = shank onto it, or plug and redrill (smaller) the hole in the hammer = moulding and use Ron's suggestion. Is the fork part of the shank large = enough to drill into and install another cut-off shank? (Won't match = the others, but might work). --David Nereson, RPT ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
