Then I use the "wetware" overpull the second time around, when it can be much less. By then, the strings are getting used to sliding over the bearings again, and one knows if they feel like breaking, as Avery said. If it is the age of upright which might have been designed for A=435, I might pull only to 435 the first time around. I carry a 435 fork for older (pre-440) pianos which seem reluctant to come up. The very first private job I did, while I was still in the course, was a big old upright way out in the country, painted white, and a major third low. I cautiously raised it a half tone each pass, came back in a week or so, tuned it again, came back two weeks later, tuned it, and it was pretty stable by then. Nothing broke (beginners luck). I tuned it every six months till I moved away. Susan -------------- next part -------------- An HTML attachment was scrubbed...
