The last two weeks have been busier than usual. Aside from the usual piano tuning jobs scattered across Sheffield, Rotherham, Doncaster and other parts of Yorkshire and Derbyshire, I’ve had six seperate bookings at the Lyceum and Cruicible Theaters to tune their pianos for rehearsals and for the premire of the play Flowers For Mrs Harris (a musical based on the novel by Paul Gallico). Yesterday evening I caught the bus into town to tune the grand piano in between performances. If anyone has seen the play on its current run, I hope the piano sounded lovely.
On Tuesday I purchased a whole new set of tools for replacing the centre pins (a job I’m required to perform for a Sheffield customer next week). Centre pins are the pins found inside the hammer flange that allows the hammer to move when a key is hit. The bushings holding the pins can become too loose or two tight, which can be remedied by adjusting the action parts (which is usually ill-advised as too much alteration will create an uneven touch across the piano – as a quick fix, however, minor adjustments can be made to the capstan screw, the let-off button or the back checks). In my two years of piano tuning professionally I have thus far been able to get by without replacing centre pins. I think this is mainly because in Sheffield (and the north of England generally) the cold and damp climate tends to swell the flange bushings (and the key bushings for that matter) making them grip the pin too firmly – when this is occurs, I apply some protek lubrication which loosens the grip (this has worked every time so far). In hotter climates the reverse is true: the dryness causes the bushings to loosen their grip. The good news is that I’m at the stage now where I’ve got all the tools I need for piano tuning and for the vast majority of repair and regulation work required on the job.
