Ed, Stan, and Cy have hit the nail on the head, well at = least glued the shank to the head. I will mention that a knurler and scoring the = shank are two different things. Personally I knurl for size and glue adherence and = I open a hole in the molding for pressure release and all the good stuff Ed = Sutton and Cy so eruditely clarified. Then I glue with Tite Bond Wood Molding Glue and wipe the excess off the top of the molding with a damp rag. My boring is slightly loose to = accomodate in-the-piano installation alignment. BTW don't forget stike point adjustment with the action bolts. I dry fit (use paper shims in the = hole if necessary) the treble hammers and adjust first = and then check after gluing. It's the big one. I doubt that there is perceptible = tonal variation with the "score the shank method" or that the shank integrity = is interrupted to any significant degree if the technique is consistent, = however, I just don't like that way because usually my shanks are already in the = butts screwed to the rail and the risk of damaging the action center seems too = great to me, and besides the little hole in the top of the molding works so = well.
