I’ve gone up ½ size as a fix for walking pins and obviously loose pins, but what I’m looking for is a way to measure friction there. Baldassin suggested there may be an efficient way to measure friction if we could determine what the spring is actually doing and subtract the difference. He wasn’t sure how to do that. It just isn’t common.<o:p></o:p> <o:p> </o:p> Richard Davenport did a class which showed how important pinning in the balancier is. He recommended 8 grams there, which was much more than is usually taught. In the class he showed how it affected the regulation to have this “right”. There are a lot more than <st1:place w:st="on">Baldwin</st1:place> that use this system. I think a few European makes do. It seems important enough, just a pain. <o:p></o:p> <o:p> </o:p> Thanks,<o:p></o:p> <st1:PersonName w:st="on">Jim Busby</st1:PersonName> BYU<o:p></o:p> <o:p> </o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: caut-bounces@ptg.org [mailto:caut-bounces@ptg.org] On Behalf Of DCyr141833@aol.com Sent: Tuesday, March 04, 2008 5:12 PM To: caut@ptg.org Subject: Re: [CAUT] Schwander balancier pinning<o:p></o:p> </div> <o:p> </o:p> <div> Jim-<o:p></o:p> </div> <div> You didn't say if your rep lev was too tight or too loose - I'm going to suspect too loose as <st1:place w:st="on">Baldwins</st1:place> have been notorious to be - as in zero friction and seriously floating rep levers.  I've repinned quite a few, and don't remember having a difficult time doing it - I just measure the pin, go up 1 full size, and take it from there.  And if you've got the odd <st1:place w:st="on">Baldwin</st1:place> with a tight rep lev, I'd protek it, as Ed suggested.<o:p></o:p> </div> <div> Debbie Cyr<o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> <div> In a message dated 3/4/2008 5:41:17 P.M.
