    Well, when you think about it, the force from the key goes through =
the elbow at a ninety degree angle, and ALL of the force goes through =
the elbow. So, as I see it, that part gets more of the stress than any =
action part in the piano, with the exception of the hammer, but then, =
why don't we see more hammer flanges break? Could be that they have a =
greater sectional density than that thin and long elbow.=20



  I guess the elbows get more of an "impact" on them than the flanges.
