You have to "untwist" the pin. Basically, it's finding the point at which you can move the pitch the same amount up or down with the lever. So, when it moves "5-10 cents either way," then it probably will be in a stable place. Give it a good test blow. If it doesn't move, you've done all you can do. It gets better with experience. A Reyburn CyberHammer would probably help. I was tuning a 1962 Steinway console yesterday, some of which have their known rendering issues. With the RCH it was not that hard at all. But with the Fujan, it was more difficult. -- JF -------------- next part -------------- An HTML attachment was scrubbed...
