I repaired an old upright bass bridge that had warped radially, (twisted) so
the upper end had no bearing on the front, and the bass had no bearing on
the rear.  I added some pianner wahr (piano wire)to take up the lack of
bearing.  I've done this on those hard wood bearing bars in old uprights
near the tuning pins and have eliminated the need for new bass strings.  In
all cases, the bearing was improved, the termination was improved and so the
bass became clear, big and boomy again.  Some have wondered wheather or not
I had buzzing because the strings were now crossing over steel instead of
wood.  I've never had that problem but I've often wondered if the hard
string that I added rubbing against the bass string would cause excessive
wear.  The bridge pins and the plate and the brass bearing bars customarily
used in production are all softer than the strings and so they don't pose a
"threat" to the strings.  We're talking cheap fixes here on old pianos that
don't warrant the expenditure of sums of money that exceed the value of the
instrument.  The repair prolongs the eventual trip 2 DUH  DUMP.  I guess you
could use brazing rod, they come in lots of different sizes.
