Hi Calin, and list, This is a update on ideas in my use of CA glue in treating loose tuning pins. Great, If you use the CA on a grand be sure to take the action out and cover the bed with news print ( paper ). Also the glue will run a lot so the use of a very fine needle ( I use my insulin micro fine needles ) will put the glue exactly where you want it to be. Use a paper towel near where you are working as each time you move the needle there may be some drips that go where you do not want them. Also a two pass approach is best just like in tuning. And in sections of perhaps 24 pins. You may want to mark the top of the pins with chalk for each section until you get the idea of where you are going to go next. Treat a section at a time with the first and go back over with a second pass. Look for the welling up of the glue to let you know to stop but also as a warning that the glue is going down a crack. In this case stop and go on to the next pin letting the glue set up a little before adding more.` You should be able to start tuning the instrument when the last pin is treated as the moisture in the wood and friction of pressure will cause the glue to set up a little. Full cure in a day or so without any activator. If you do an upright you may want the instrument to be on its back, but I have treated a few pins with the needle with the instrument standing. It is a pain in my back to do it this way but a few pins are not too bad. Joe Goss imatunr@srvinet.com www.mothergoosetools.com
