A piano string coil lifting and setting apparatus comprising:
- a slide hammer portion;
- and
- a string engaging portion extending from said slide hammer portion, said string engaging portion intended to engage a piano string coil wrapped around a tuning pin and transmitting a force from said slide hammer portion to said piano string coil for purposes of adjusting the tension of said piano string coil.
A piano string coil lifting and setting apparatus comprising:
- a main bolt member having a head portion and a shaft portion extending from said head portion, said main bolt member defining a bore across a longitudinal axis of said main bolt member, said shaft portion having a bottom section comprising a downward bolt detent, said head portion comprising an upward bolt detent;
- a rod intended to reciprocate through said bore, said rod including a upward rod detent for contacting said upward bolt detent and applying an upward force to a piano string coil that is wrapped around a tuning pin, said rod further including a downward rod detent for contacting said downward bolt detent and applying a downward force to said piano string coil, said upward rod detent and said downward rod detent being sized larger than said bore and situated on opposing sides of said bore;
- and
- a string engaging portion extending from said rod, said string engaging portion for engaging said piano string coil and transmitting at least one of said upward force and said downward force to said piano string coil.
A method for manufacturing a piano string coil lifting and setting apparatus comprising:
- forming a bore substantially across a longitudinal axis of a main bolt member, said main bolt member having a head portion and a shaft portion extending from said head portion;
- disposing an anchor shank within said bore of said main bolt member;
- securing said anchor shank within said bore of said main bolt member;
- and
- coupling a tool shank to said anchor shank, said tool shank having a string engaging portion extending therefrom.
