Hi Conrad, A silly question but could you tell me what is a wafer ? Thanks, Pierre Gevaert -----Message d'origine----- De : pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] De la part de Conrad Hoffsommer Envoyé : lundi 17 novembre 2008 12:38 À : pianotech at ptg.org Objet : Re: [pianotech] ivory replacements with wafers intact using metal key plates Debra Feiger wrote: > Can someone please give me the procedure for replacing individual > ivories which are in good shape along with the wafers.

Thank you. > > Debra Feiger, RPT > -clean all residue from underside of ivory to be re-installed -clean keytop, especially including the front edge of the ivory tail (if still in place) Ugly black lines result if you don't. -make sure dry fit of wafer and ivory results in a flush joint to the tail - scraping ivory to eliminate a stair step is not fun. DAMHIK -soak wafer in water for a few minutes -position wafer and ivory on key -place plate on ivory -tighten with clamp, ensuring that the ivory has not shifted out of position -recheck ivory position (also in the DAMHIK category) -using alcohol lamp, and holding key upside down, heat plate almost too hot to touch -let cool -remove clamp/plate -trim excess wafer (Folks, did I forget anything? - it's been a long time since I did it this way) -- Conrad Hoffsommer, RPT - Keyboard Technician Luther College, 700 College Dr., Decorah, Iowa 52101-1045 1-(563)-387-1204 // Fax 1-(563)-387-1076 If I had multiple personality disorder, my resume would make more sense. -------------- next part -------------- An HTML attachment was scrubbed...
