關於「雷諾」弦槌大家認識有幾多？

　仲有整音？ 　


調整、調律的工作完成後，便是整音的工作。這項工作是要使鋼琴整個音域的音色與音量都能整齊、合一，展現整台琴特有的生命力。
整音的工作主要有三項，即琴槌的整形、硬化劑塗布和針刺等。第一項工作是要將琴槌正確的形狀整理出來，使毛氈的表面與其張力統一，以使發音與音色平均。硬化劑塗布目的是要增加毛氈的硬度，以改善毛氈過於柔軟的情形。至於針刺則是要糾正毛氈過於銳硬，使毛氈的纖維鬆軟，音色變軟。
在整音的同時，並尋找此勤音色語音量最佳之處做為基準音，按此基準音再調整整體的音色與音量。

So, great, you have finally discovered the internet, where you can find out all these information. Kudos to you!
However, knowing it and doing it are two separate issues. I sincerely hope that your bite is as strong as your bark. Also, keep an open-mind, especially when dealing with press materials - everything you've said comes from Renner's press kits (and by the way, it's Premium Blue, not Preniun), and certain details are a wee bit exaggerated, although I do think that when restoring old pianos (Steinway, in particular) nothing comes close to Renner PB. The technician has to have sufficient experience in using them before making any major restorations on old pianos.

Thanks for the tidbits on Abel, I wasn't aware of their connection. I first came in contact with Abel parts with a Japanese piano restorer who specializes in restoring 19th century fortepianos. I am not an expert in this, but I did see the excellent T-rivets and covers done by Abel technicians on old hammers.

你自己都答la~
