I don’t know if it is possible to find such tuning pins nor if it these would hold better.<o:p></o:p> There is some explanation on the lest front side of the soundboard near the basstrings but I think this is only to explain how to change a string.<o:p></o:p> I’m also interested to know how to make this kind of pins tight again.<o:p></o:p> <o:p> </o:p> Like some use ca glue for wooden pinblocks would it be possible to use a kind of product like Locktite for metal threads ?<o:p></o:p> This is used for making the threads tighter and exists in several strenghts. <o:p></o:p> Of course this may sound stange for using this kind of stuff for historical pianos but I can’t see another way exept maybe make threaded pins that are a little bigger or maybe a better choise to change the wooden part of the block (beech)so that at least the pins get some new grip there.<o:p></o:p> <o:p> </o:p> In this way it would be possible to clean and reuse the original pins.<o:p></o:p> There are many of those Boudoir grands remaining today so I would eventually be possible to find another similar instrument for using spare parts.<o:p></o:p> <o:p> </o:p> <st1:PersonName ProductID="Pierre Gevaert" w:st="on">Pierre Gevaert</st1:PersonName><o:p></o:p> <o:p> </o:p> -----Message d'origine----- De : pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] De la part de John Delacour Envoyé : dimanche 3 août 2008 19:58 À : <st1:PersonName w:st="on">Pianotech List</st1:PersonName> Objet : Re: Broadwood broken tuning pin <o:p> </o:p> At 15:28 +0200 3/8/08, stephan van meirhaeghe wrote:<o:p></o:p> <o:p> </o:p> >Hi list,<o:p></o:p> ><o:p> </o:p> >I'm now restoring a Broadwood grand 'Boudoir' and had to remove all <o:p></o:p> >the tuning pins because to rusty and not possible to tune...<o:p></o:p> >Anywone had similar problems?And where can I find similar pins?Or do <o:p></o:p> >I need make new ones?<o:p></o:p> <o:p> </o:p> Are you talking of the threaded pins that screw into an iron plate? <o:p></o:p> If so, send a photo.
