Restoring a fortepiano for the Carl Bechstein Foundation. 17 Calculating the string tension

The original hitchpin liners have been glued back in and now the original hitchpins are being put back in their own holes. The instrument gets new strings. The windings on the tuning pins are being made with left-turning drilling machine. Michael Latcham, who did research on Hofmann and Stein, is with us for a few days.
Since 2019 the Carl Bechstein Foundation in Berlin is building up a collection of historical keyboard instruments, reflecting the history of the piano. All instruments will be in perfect playing condition and in this film-series you'll see the whole proces of a restoration, starting from a total wreck. This fortepiano was built around 1795 in Vienna by Ferdinand Hofmann (1756-1829).
From this restoration film series are two versions, one with a German voice-over and this one with an English voice-over.
