Hi all! In the discussion following a recent PTG chapter meeting, the question came up as to why piano manufacturers don't cast and machine plate flange faces along straight lines and/or perpendicular angles which would be more easily matched/duplicated in the corresponding faces of the pinblock. I assume there's a good reason behind all of this but am curious as to what it might be. Regards, Alan Crane, RPT Wichita State University crane@twsuvm.uc.twsu.edu
