If you cut the old board out with a router you can then use it as a template to cut the panel to rough shape. My ribs are fitted after the panel is fitted to the case. There is no need to have the ribs there to support the panel. This whole layout process would be very difficult to explain in words. Maybe some day I will take a few photos. -- John Hartman RPT John Hartman Pianos [link redacted at request of site owner - Jul 25, 2015] Rebuilding Steinway and Mason & Hamlin Grand Pianos Since 1979 Piano Technicians Journal Journal Illustrator/Contributing Editor [link redacted at request of site owner - Jul 25, 2015]
