Dick, When I have used Marine Spar Varnish I use it, let it dry in hole over night and replace with one size up if the pin is good, the same size if it is great. I drive it in, I don't turn it in. I never swab the pin though...just the hole. The pins seem good and have never had one still seem jumpy. Ed Tomlinson Tomlinson Tuning and Repair Dick Writes.... Do you replace the tuning pin immediately after swabbing the pin hole with varnish? Or do you let the varnish dry? Do you also varnish the pins? Do you drive the tuning pin back into the block (as is normal) or turn it in? Seems as if driving it in would scrape off the varnish on the sides of the hole. Assuming the pins were acceptably tight at the get go, do you still replace with larger pins. Piano is in really good shape except for this problem. Not good enough piano (spinet) to justify replacing the block. Thanks to all Dick Day >>
