The tuner strikes the key, energizes the string, and instantly begins to turn the pin. This size is a good balance between snug fitting and being large enough to fit many piano's pins (including yours, which appears to have a relatively large tapered section.) Make sure the tip is removable so you have options if you decide later to try different sizes. The first might be called the ' wrench and pound ' method. Take Tim's advice and get a lever with a #2 tip, which is the default for many makes and models.

One of these is a respected teacher at the PTG conventions, which I know because I was in his class when he described his technique :-) But again, it is a personal choice. 'impact,' whether they prefer a snug fit or more play, how much swapping of tips they're willing to do to get the fit they like, etc.Д®ven if there was a correlation, the size of the star opening of the tip and the rate of taper varies between makers, even for the same size designation.Д¬aveat: I am aware there are some piano tuners who take a snug fitting tip very seriously, to the point where they try multiple tips on every piano they tune.

The most common sizes of tips are denoted #1, #2, and #3 and have no correlation to the diameter of tuning pins. However, that measurement has little to do with the choice of a tip for your tuning lever. I note from your photos that your piano has enough clearance between the bottom of the coil wound around the tuning pin and the plate/bushing that you could probably get a digital caliper in there and measure the diameter directly, if you wanted that value.
