バイオリンのあご当て交換
Violin Chin Rest Replacement
ただ、あまりの値段に最初来たものはネジ部分が目視で曲がっていて組み立て不能。返品し、再度同じものを購入すると、今度は大丈夫。However, due to its ultimate price, the 1st one delivered has bent screw that cannot be assembled. Hence I returned it and ordered the same one once more to find the 2nd delivery looked fine.
レンチで逆ねじに気を付けながら固定する。締め上げるとき、力が表・底版でなく、側板にかかるよう、ギリギリまで端にセット。また、締めすぎないようにレンチに加える力を注意。後で側板の上下に指で強い力を加えてみたが、かなりの強度を持っているようで、固定時の締め上げ力には耐えられそう。Fixed by wrench taking care of the reverse screw. When making final wrenching, put the chin head very near to the edge to avoid applying force to top/bottom but only on side. Also paid attention not to bind too much when binding by wrench. Later, I confirmed that side has rather big strength by pushing side plate from top/bottom by fingers, so I believe violin can stand the force applied when I fixed the chin head.
バイオリン本体に触れる金具と、あご当て部分に家具の足に使うフェルトを切って張り付けた。また、前後するが、あご当て部分の穴は大きめだったが、差し込むだけで、締め具の圧力で十分固定された。今後、もし外れた場合は、接着剤などで充填する予定。Note that I cut felt buffer for furniture legs and attached them on the bottom of chin rest as well as on the bottom of binding metal. Also note that holes on chin rest are bigger than the binding bar diameter but just by sticking them in, the chin rest was fixed sufficient by the binding force. Going forward, if chin rest goes part from violin body by any chance, I may use chemical glue to fill in the holes.
