<div>Bill,</div><div><br></div><div>Thank you for this: most interesting. We conversed about stretch tuning when you were investigating this subject originally. You said at the time Bengeo was considered the first Taylor stretching exercise, but Andrew Higson checked the tuning dates for Evesham and found that work (also in 1951) predated the Bengeo tuning by a month or two. Geoff Hemming was approached by Paul Taylor about stretching the two trebles, as he wanted to investigate the effect, but said they would be tuned down to datum if Geoff didn’t like them. Geoff did, and they remain as Paul Taylor originally tuned them. The treble’s nominal is +19c above tenor datum and the 2nd is +12c (JT figures: yours differ only fractionally).</div><div><br></div><div>I see Bengeo’s nominals are stretched throughout (like Tewkesbury), so Paul Taylor may have been investigating two types of stretching at the same time: one with just trebles of a 12 and the other a gradual stretch throughout.</div><div><br></div><div>Chris Povey<br></div><div data-signatureblock="true"><div><br></div><div>Sent from Windows Mail</div><div><br></div></div><div style="padding-top: 5px; border-top-color: rgb(229, 229, 229); border-top-width: 1px; border-top-style: solid;"><div><font face=" 'Calibri', 'Segoe UI', 'Meiryo', 'Microsoft YaHei UI', 'Microsoft JhengHei UI', 'Malgun Gothic', 'sans-serif'" style='line-height: 15pt; letter-spacing: 0.02em; font-family: "Calibri", "Segoe UI", "Meiryo", "Microsoft YaHei UI", "Microsoft JhengHei UI", "Malgun Gothic", "sans-serif"; font-size: 12pt;'><b>From:</b> <a href="mailto:bellhistorians@yahoogroups.com" target="_parent">bill@hibberts.co.uk [bellhistorians]</a><br><b>Sent:</b> Sunday, 15 July 2018 17:39<br><b>To:</b> <a href="mailto:bellhistorians@yahoogroups.com" target="_parent">bellhistorians@yahoogroups.com</a></font></div></div><div><br></div><div dir="">

<p><p>I have just completed an investigation into stretch tuning by Taylors from the 1950s to the 1970s. It's an extension of the work I did a few years ago, but extended to cover 6,110 bells in total, and 1,592 Taylor bells. The article is online at <a href="http://www.hibberts.co.uk/stretchtuning.htm" target="_parent" rel="nofollow">http://www.hibberts.co.uk/stretchtuning.htm</a> . The key points are:</p><p><ul style="padding-top: 0px; padding-bottom: 0px; margin-top: 0px; margin-bottom: 0px; list-style-type: disc;"><li>a claim by a bellfounder of the ability to <span style="font-style: italic; word-spacing: normal;">independently</span><span style="word-spacing: normal;"> tune the upper partials in a bell is probably not justified</span><br></li><li>the actual tuning figures of five complete Taylor peals of 8, 10 and 12 match closely the theoretical predictions of strike pitch shift due to thick trebles.<br></li></ul><p></p><p>Clearly Paul Taylor was hearing and tuning strike pitches when he adopted stretch tuning. I wonder how he was able to measure and tune them so closel
y, and whether he had a method of calculating them from the bell partials?</p><p><br></p><p>Regards,</p><p><br></p><p>Bill H</p><p><br></p><p> </p><p></p>
