<< For those of you who have installed a "Renner" back action on an S & S "D", do I need the special $40 drill bit? >> The long bit makes the job easier, and if you are going to do a few of them, it is certainly worth the expense. It not only is long enough to easily go by the tray, it also leaves a taperedhole with a slight countersink at the top. I think it is a lifetime tool, and mine has about 10 back actions on it and still works well. Ed Foote RPT www.uk-piano.org/edfoote/ www.uk-piano.org/edfoote/well_tempered_piano.html
