-----Original Message----- From: Greg Graham <grahampianos@yahoo.com hey Greg All good questions & many good answers so far. I also use the sound or amount of sustain plus the qualiy of sound of the treble hammers in the shifted position as another guide to optimal hammer placement. If the tone is thin and whiny accompanied by lackluster power, the hammers need to come forward. Use the description Jon page describes. The area around c-6 is usually the note requiring the furthest excursion towards the keys rsulting in , yes, a horshoe in the hammer line but a much improved sound. Generally this line starts about g-5 and extends to appro. f-6. This is on Stwys but have seen this anomally on many other makes. BTW any piano worthy of a new set of hammers is worth this minor extra process to achieve optimum results. Hey why not? Dale Erwin Dear jigless grand hammer hangers, The discussion on hammer hanging jigs last week prompted several of you to suggest that a straight hammer line is not optimal for sound. You say each hammer (at least the top two or three octaves) could or should be set at the strike point that produces the best sound. You are tweaking the placement of many or even all hammers, rather than placing C88 and using a straightedge to the bottom of the piano. Someone mentioned that this level of attention makes sense for very high quality instruments, and I'm interested in working toward that end of the quality spectrum...eventually. The question bouncing around in my inexperienced head is this: >From a practical perspective, what methods do you use for finding the aurally ideal strike point of individual hammers? How do you manipulate the hammer on the shank? Do you slip the hammer on the shank dry but snug, put the action in the piano with the cheek blocks in place, then tap the hammer in and out somehow through the strings? Pull the action, adjust, replace action, repeat? Will a dry fit hammer handle heavy blows without moving? Are heavy blows required? Do you glue on the hammer and pop it off again if it isn't right? Will a dry fit hammer sound the same as one that is glued? Do you use paper strip shims between the hammer and shank to hold the hammer fast while testing? Do you do several or even all hammers at the same time? Do you have someone "in the hall" listening, or do you go with what you hear from the keyboard? Does your method take a week, a day, an hour, two minutes? Looking for some how-to. Thanks. Greg Graham Brodheadsville, PA __________________________________________________ Do You Yahoo!?
