Thanks for the input on the hammer installation question, everyone. I agree with one poster, who wrote it's too complex of an occasion to answer simply. For me, the main difference between grand and upright hammer hanging is the generally greater prep and post work needed in my experience for grand hammers. The stock American grand hammers, which I often use for more moderate quality baby grands, are drilled with tiny holes that require either being enlarged or the shanks dramatically reduced, or some combination thereof (can someone explain why stock American grand hammers come with such tiny holes, when virtually all grand shanks are thicker than upright shanks, and American stock upright hammers come with larger diameter holes?) Another problem for grands in my experience is the affect on the action that hammers of slightly different weight cause (I rarely notice it on uprights, perhaps because such installations are generally performed on large uprights with longer keys), so hammer-tail shaping, key-weighting, or action adjustments often seem necessary to make the grand action work decently. But perhaps part of the problem is due to the grand hammers I often use (though I've had the same weight problem with more expensive grand hammers also). Thanks for any thoughts or suggestions -- JeffO
