[pianotech] palm nailerette

Hi John,

Good point you raise.? On our Steinways, Bosendorfers and rebuilds, yes, the bridge pins have been filed (unlike on the Yamahas).? That could contribute to the pattern I have noticed.? Can anyone else corroborate this?

Thanks,

Alan Eder

Have these pins been filed? ?I've wondered if perhaps the filing moves them around in the hole, and contributes to looseness later on.

Speaking of?getting bridge pins down in their holes, has anyone documented any difference between driving them in by hand vs. pushing them in (as, I am told, many of the larger piano manufacturers do) in terms of pin looseness down the line.? I ask because when replacing a broken string, I routinely give the bridge pins involved a tug.? Most of the bridge pins from "hand made" pianos (in which the pins were, presumably,? pounded in) come right out, so I glue size.??In the same building, I have yet to encounter any loose?bridge pins on the mass-produced pianos present (in this case, all Yamahas).? And, yes, strings do break on the Yammies?as well.
