Understanding the Types of Cracks
Cracks in the Riser and Limbs
Cracks in the riser and limbs can be particularly challenging to repair. If the crack follows the grain, it can be wrapped with artificial sinew or silk/linen soaked in glue to prevent spreading. However, if the crack goes against the grain, it may be more difficult or impossible to repair.
Cracks in the Head
The Vulnerability of the Head
The head of the bow is a critical and vulnerable area. It must be strong enough to withstand the constant pull of tightened hair but flexible enough for expressive playing. The head can split off from too much tension or a drop to the floor. After a serious drop, have a valuable bow checked for tiny cracks visible only to the trained eye. Repairing can extend the useful life of the bow, but a broken and repaired head reduces value by 50 percent.
Assessing the Value of Repair
Is the Bow Worth Fixing?
Routine bow repairs, such as rehairing and replacing thumb leathers, eyelets, or pearl slides, are worth doing for any bow that you enjoy playing. However, the cost of more time-consuming repairs, such as reattaching the head, replacing the headplate, or restoring a crumbling frog, can soon overtake the value of most student bows. Consult your repair person and insurance agent to help you make a sensible decision.
