The steep sharp angle seems to be of factory orgin but could have been = worsened by slight tapping in of the pins. The wire breaks due to the = added torque of the wire riding up on the coil.Makes that string harder = to tune also. That result of tapping pins, caused me to use CA glue as my first remedy = and only tap pins if there were only a few, and those few were not on = the steep decline. <g> Joe Goss RPT Mother Goose Tools imatunr@srvinet.com www.mothergoosetools.com ----- Original Message -----=20 From: Dave McKibben=20 To: Pianotech=20 Sent: Sunday, October 30, 2005 9:02 AM Subject: acrosonic string breakage List: I just tuned a Baldwin acrosonic that by S/N was 15 years old, but it = appeared to be older. My question revolves around the attached picture ( as best I could = draw the problem ). The strings A2, A#2, G2, G#2, F2,F#2 and C3 all broke when doing an = 80-100 cent pitch raise. I warned the owner that I could tune it to less than A440 to help = reduce string breakage but she wanted it at A440 so she could play with = other instruments. All the strings were on the bottom row of tuning pins, which creates a = steeper angle to the Vbar. The angle to the Vbar was so great, that the last coil on the pin was = trying to cut across the previous adjacent coil on the tuning pin. ( = see pic ). It appeared to me THAT is why the strings broke, each one right at the = pin coil. It did NOT appear that the pins were pounded in, creating a steeper = angle. My question is: Is this normal pin / string coil configuration for acrosonics? has anyone seen this before, and what might the problem and fix be? I'm sure someone on here knows the answer ! Thanks much Dave McKibben -------------------------------------------------------------------------= ----- _______________________________________________ pianotech list info: https://www.moypiano.com/resources/#archives ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
