I'm trying to figure out why a grand action that seems to be regulated
correctly, in terms of all the various adjustments, still has no hammer
rise, even with the repetition springs compressed to almost max. Some of
them rise just the tiniest amount. On most actions, upon letting up of
pressure on the key (but not letting the key up), they should rise from where
they check, up to but not past the point of let-off. But these barely
rise 1/16" if at all. The checking distance isn't abnormally
high; the rep. springs aren't weak; the rep. levers aren't pinned exceptionally
tight; there's no gunk or goo hindering them; I suppose powdered Teflon on the
knuckles might help a bit, but still . . . . I'm not sure what gives.
