Delayed/internal fracture of bows not visible from outside?
Hi all: For the bow makers on here, is there such a thing as "delayed" crack or split after a bow had been dropped? (ie. the bow looked fine outside with no damages at all but fractured internally, and later on splits/cracks)
Just wondering since I have heard of how bows suddenly splits at the tip.
Not a bow maker, so I can only speculate. If a fracture is not visible, until it breaks, how would you know? Short of Xraying your bow, and even then, your guess is as good as anyone else's. Theoretically it is possible I suppose that micro fractures would weaken an area, which under tension can break eventually. Even if it does, what would you do other than wait that it breaks to fix it? Some say that the "bad" habit of pointing parts on the partition with the bow can eventually lead to a splitting of the tip because of such invisible micro fractures.
If it is not a new bow it might have been damaged before and expertly repaired. (It was not dropped.)
I am personally skeptical of the possibility of internal fractures in a bow. The stress of the expansion inside would certainly just crack it good all the way through. Pernambuco isn't known for its stretchiness.
