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.
