<html> <body> Mr. Oorebeek, I'm curious.  I dealt with just such a problem in an old upright and I was advised that larger tuning pins might exacerbate the problem by increasing the leverage the string has on the pin.  In this case CA glue was acceptable for an old upright that the customer could just afford.  I am curious if anyone has comments regarding stability problems after using larger diameter pins. Curious in New Mexico, Andrew BTW, if you use CA glue, use a respirator (canister type ) not a dust mask and ventilate the area well (just because it doesn't have a disagreeable odor doesn't mean it isn't nasty).  Also it is nasty to use, apply with a syringe (farm supply for livestalk use works) and keep plenty of paper towels by for cleanup.  Prevent runs with tape and paper.

The problem is I have absolutely no idea what CA glue is. Maybe in UK we have an equivalent. So... Could someone please describe this glue... What colour is it? ... what consistency? ... what smell does it have?... Is it water-based and therefore thinned with water before use?... how large are the containers it comes in? .... is it a resin glue? ... is it something like PVA woodworking glue? (which stuff can be thinned down with water in a bucket to "size" concrete before laying wood-block flooring..:-) Is it another name for that terrible glue called "Cyano-Acrylate" as used in the plastics industry and can glue your fingers to your nose (or other parts of the anatomy). With the same initials this is my guess. It is this very "thin" glue which comes in quite small white plastic bottles with a dispensing nozzle and has a limited "shelf-life". Question:  If you had an old (1895) S&S model "B" 85 note grand with replaced tapered legs and loose Bass tuning pins... would you be tempted to go the CA route? I have just such a problem at the moment but I rather think I prefer the replacement strings and pins option on an S&S of that age. Regards from the black cold Sussex Downlands Michael G (UK)  </blockquote> I have said this before, but, reading your words, I again wonder about the following : Why do we consider using a CA glue treatment, when tuning pin problems actually must be solved with an over size tuning pin and new strings? Is the use of new tuning pins and new strings such a problem? Isn 't it better to tell your customer to pay for a complete re-stringing? If the customer refuses to pay for pins and strings, isn 't it then better to politely, and in a friendly manner, tell your customer that a re-stringing is the final answer? In my experience, new pins and strings are far more preferable, and durable, and in my +30 years  I may have lost a customer here and there because of my professional principles, but I am 55 years old, still making money, and I will probably do so until I fall down. So why not go for the very best technical answer? friendly greetings from André Oorebeek Amsterdam - The Netherlands 0031-20-6237357 0645-492389 0031-75-6226878 <a href="http://www.concertpianoservice.nl/" eudora="autourl">www.concer= tpianoservice.nl</a> <a href="http://www.grandpiano.nl/" eudora="autourl">www.grandpiano.nl</= a> </blockquote></x-html> </blockquote></body> </html>
