Robin Harrison Posted Sunday at 04:43 PM Share Posted Sunday at 04:43 PM Can anyone help with the issue of replacing the missing button cap..... I do not have it. (Also never noticed the little holes on the side of the shaft, they are from a Lachenal tenor.) Thanks as always. Robin Quote Link to post Share on other sites
alex_holden Posted Sunday at 04:53 PM Share Posted Sunday at 04:53 PM I think the "touches" are silver - not sure whether fine or Sterling, soft-soldered onto the end of a tube. The little hole lets gases generated by the soldering process escape. I expect a local jewellery-maker who works in silver could sort it for you. Quote Link to post Share on other sites
d.elliott Posted Sunday at 06:56 PM Share Posted Sunday at 06:56 PM Hello Robin, Are these bone buttons with metal caps? do you have a picture of a complete button assembly, or is that what we are seeing on the lower key? What is the diameter of the key body? Quote Link to post Share on other sites
Alex West Posted Sunday at 10:59 PM Share Posted Sunday at 10:59 PM Robin I had exactly the same issue with a Lachenal New Model Duet which I restored. As Alex H suggests, the local jeweller helped me out and it wasn't too costly either Alex West Quote Link to post Share on other sites

Dave......all metal and the lower one is a complete unit but the attached image maybe easier to see. Diam =4.5mm Quote Link to post Share on other sites
gcoover Posted Monday at 08:00 PM Share Posted Monday at 08:00 PM The quick fix is to switch it out with another button from a note you never play, maybe way up in the top end? Gary Quote Link to post Share on other sites
Robin Harrison Posted Monday at 09:46 PM Author Share Posted Monday at 09:46 PM Could do Gary, but this is a restoration so got to do it right! Thanks for the help everyone.....just took it to a jeweler who will laser weld a cap on. Will post the result when complete Robin 1 Quote Link to post Share on other sites

I am curious to find out how much I will pay for this modern technology........ Quote Link to post Share on other sites
d.elliott Posted Wednesday at 04:12 PM Share Posted Wednesday at 04:12 PM Some time ago I had some SS caps made to be bonded in place, they work well but they are the wrong sort silver to look at. It will be interesting to see what the cost will be. Dave Quote Link to post Share on other sites
