Plate break after restringing

Absolutely right.

Then if you contend they are hard to break, why do you think the tech,
during a routine restringing, "did something" to cause it to break?  Like
you say above and below, they are hard to break.  Now you are contridicing
yourself.

It is simple.  The years of pressure put the test to the metal.  The break
will occur where there are any imperfections in the manufacture process.

I contend that the only way a plate can break (during routine rebuilding) is
because IT WAS DEFECTIVE.  My proof is in your own words above.
