Dear Gents, Sorry for the late addition to this thread. I have just resubscribed after many months absence. During my tenure as Samick Service Manager in Canada (1988 - 1995), I counseled many of our dealers and their technicians to employ the 'wedge' technique on the many Samick grands which arrived with poor pinblock fit (at that time). The technique was the subject of an article in the Journal many years ago. That a full fit of block to flange is necessary remains the subject of considerable debate. Those of us engaged in the full rebuilding of grand pianos would not dream of installing a block which did not make 100 percent contact with the flange (I believe the minimum requirement is contact at least every inch) and we all expect the same paradigm of reputable manufacturers. Whether or not this fit has been proven to be crucial to future tuning stability, one thing is for sure: If the fit is perfect, it will never be a factor. To be prepared with a cost-efficient and serviceable repair in those cases where the piano presents with a less-than-perfectly fit block will make you a hero to the dealer and a welcome friend of the manufacturer's service manager. Now, coincidentally, I am heading out to the workshop to make a pile of shavings from a maple plank ... cutting wedges for my client's 1986 Samick grand pinblock! Best regards from the frozen Canadian prairie! Stan Kroeker, RPT
