The photographs in this gallery document an action overhaul that I completed on a Canadian-built Heintzman bourdoir grand at Brandon University in 2011.
Top view of keyboard
New, one piece key tops, hand notched and filed for best finish. Material has been buffed out to achieve less of a "plastic" feel.
Top of keyboard #2
Wood keys individually cleaned and numbered for easy identification. Capstans polished and lubricated for low friction.
Side of keys
Keys were widened with veneer to correct excessive gaps before new key tops were installed.
Reconditioned hammer shanks
Brand new Tokiwa knuckles were installed on original shanks. They were lubricated with TFL-50 and Teflon powder for low friction. Shank centers were repined to close friction tolerances, and screws were polished to like-new look.
Front view of keyboard
High-end Crescendo felt punchings for consistent key dip. Key pins were polished and lubricated for low friction.
Ronsen hammers, made with felt from the Bacon Felt Company, were installed due to their resilient tone. In a market flooded with harsh-sounding instruments, this is a welcomed change!
