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.</div> <div><br></div> <div align="center"><img src="cid:a05100300baec753f2349@[61.8.27.181].1.0"></div> <div>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;</div> <div><br></div> <div>http://www.mitutoyo.com/cat2000a/l-39.htm</div> <div><br></div> <div>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.</div> <div><br></div> <div>Best,</div> <div>Ron O.</div> <div><br></div> <x-sigsep><pre>-- </pre></x-sigsep> <div>_______________________<br> <br> OVERS PIANOS - SYDNEY<br> Grand Piano Manufacturers<br> <br> Web: http://overspianos.com.au<br> mailto:info@overspianos.com.au<br> _______________________</div> </body> </html>
