Will straightening violin bow change the camber?
Just need an advice about straightening my Jules Fetique bow that I recently purchased from an auction. It has excellent playing qualities but it has a bend towards left (player side). I know that it can be fixed by a professional but I am worried that the characteristics or the camber of the bow may change. If I like the bow how it is play, should I still bother to straighten it? Thanks everyone!
If it’s not a really bad warp to the left then it might actually be okay and there’s no need to fix it unless you really want it straight. I’ve had luthiers tell me that a slight warp to left is okay for violin and viola bows because it can cater to the way we play. It would be the opposite for cellists where a slight warp to the right would be best.
I was going to respond to the OP saying that my F.N Vorin violin bow had a slight warp to the left. So I took it from the case and looked at it and then tightened it to compare the stick with the hair ribbon (which is always straight) and found it is not warped. I had not used it much for some years but had it rehaired during the pandemic.
As already said, A) to the left may be a
I would call Josh Henry and ask his opinion.
Some re-hairers will build in a small curve to the left under tension. The idea is that your index finger will push the stick down (to the right), so you get more to work with.
Straightening and recambering are two different things. When a stick is warped to the left or right it can be brought back into straightness without affecting camber. Recambering deals with the curvature of the stick along its length.
Tks for the opinions. They give me the comfort to bring my bow to be straightened by a reputable bow maker/repairer in Toronto without affecting the camber. Just one more thing, if my Jules Fetique is not very percussive in my playing, will the bow repairer be able to make the bow behaves "quicker" after straighening it? The bow makes my violin sound very elegant because of its richness and enhanced overtones, but it is relatively "slower" when compared with my usual Malo bow. Perhaps it is a matter of for me to learning the bow. It weights 61g.
Responding the above post, I recently tried quite a few fine old French bows and I felt some has quicker spring (healthier) even if it's supple, while some are a little more tired despite the notes came out crisp, ricochet is relatively slower.
I have a very nice German bow made by Christian Wanka around 2005, which I have always loved for its warm and rich sound and its general versatility. I noticed that it seemed to develop a slight warp to the left several years ago. When I brought it in for re-hairing in Ottawa, by an extremely skilled luthier, Charline Dequincy -- now at Reuning in Boston, alas -- she took a quick look at it, and said she could probably correct it with an adjustment of the hair. Six years, and as many re-hairs later, the warp has never reappeared.
