Hello, I have begun to do my own hammer work. I am challenged at this point by determining bore angles from the original hammers. I am boring for a Yamaha C-7 and have found the bass angle to be 9 degrees. Does this seem correct? Also, if anyone has the angles for this piano I would appreciate it so I can practice reading my angle guide knowing what I should be expecting. I am sure that these are the original hammers. Any help is greatly appreciated. Thanks, Steven HoppMidland, TX -------------- next part -------------- An HTML attachment was scrubbed...
