cracks in rim

[Dean May]

True, but consider that they string it up and tune it before they put on the
outer rim. While it does not prove that it was designed to do so it would be
pretty poor design work if they didn't count on it handling all the stress.
I mean, we've never seen poor design work before in pianos, have we? ;-)

Dean, I think your logic is faulty. "...they make them with that way, with
the outer rim assembled at the end. That means the inner rim must be
designed to handle all the stress by itself with the outer rim serving
primarily a cosmetic function." 

 

Whereas I will agree with you that the inner rim should be designed to
handle all the stress, I find it illogical to assume that the inner rim must
be designed to handle the stress.

 

Big difference IMHO   ;-)

You take the action out, lid off and lid hinges off the rim. Stand it up on
the side as normal, then tip it on over. Make sure you have appropriate
padding in place for where it comes down. 

 

First time I saw such cracks I realized that they make them with that way,
with the outer rim assembled at the end. That means the inner rim must be
designed to handle all the stress by itself with the outer rim serving
primarily a cosmetic function.
