Fixing the Piano again

Once again the broken parts of the piano have become annoying enough to tear it apart and fix them.  This time I have a worn piece of leather on one of the hammers that I've never had to fix before - I decided to tear it off, turn it around, and hope for the best.  Another little pin was outta place - an easy fix.  While waiting for the glue to dry on the felt I ran across this article: Worlds Smallest Piano Wire - which is interesting - but I've never worked on the wires (the musical wires) in my piano - I leave that technology to the tuner guy.
