St=E9phane. ----- Original Message -----=20 From: Ron Overs=20 To: Pianotech=20 Sent: Sunday, May 18, 2003 2:17 AM Subject: Re: strings measures St=E9phane, Does anyone have a good trick for acurately measuring string = diameters while still in the piano ? I normally use a micrometer on broken strings, but it is impossible = to put it between the strings that are still in place. I found that = caliper measurements are not accurate enough for proper use. What you require is a multi-anvil micrometer. I have been using one = for many years to measure the strings in the piano. It is particularly = handy when you are dealing with a broken bass string, since you can = measure the cover and core diameters of the adjacent strings in the = piano without letting the tension off. The above image, of the Mitutoyo 117-101, 0-25 mm metric micrometer = (they also make an Imperial measurement version), was taken from the = Mitutoyo website at; http://www.mitutoyo.com/cat2000a/l-39.htm These micrometers come with a round and flat anvil. The round anvil is = used for measuring tube wall thickness. They are more expensive than a = standard micrometer, but you'll have it for the rest of your working = life. My multi-anvil is a Starrett, but the Mutitoyo is better made.
