Young Chang started doing this in the mid 90s, don't know if they still do.
They used a brass rod instead of steel. Music wire on brass is self
lubricating.

Subject: Re: [pianotech] Capo Bars
Good question... and I'm looking forward to reading the replies. FTR,
Bohemia pianos, a spinoff of Petrof after the splitup of Czechoslavakia
actually did do this for a while... I'm unsure if they still do. They
used some kind of bronze alloy I believe. Perhaps its a question of
tooling and expense ?

Why do manufacturers harden capo bars rather than cast (or grind)
the underside of the strut flat, rout out a groove to receive a
steel rod of proper radius, shape and hardness and insert it there
where it could, when it's worn, be easily changed and where the
consistency would be more easily controlled. Is there a compelling
reason not to do it that way?
