Checking Your Bow for Cracks
As students get settled into the new school year, now is a good time to take a good look at your bow and get any needed maintenance done. Give your bow a thorough examination from the tip to the frog using these guidelines to help you identify some common problems and make the best decision for you and your bow.
Cracks can have a variety of causes. The most common ones are over tightening the bow, leaving it tight for long periods of time, or forceful impact (e.g. hitting or dropping the bow.) Start by looking at the tip--the tiny white piece that helps to secure the bow hair into the head of the bow. A cracked tip may need to be replaced as leaving it cracked can affect the structural integrity of the rest of the bow. It can also lead to difficulties with the bow hair remaining securely fastened to the tip. After looking at the tip, look just below the head of the bow. This is the most common place for cracks, especially in student bows, due to over tightening or blunt force trauma. A bad crack in this location can cause the head of the bow to break off due to tension. A bow that has had the head reattached will typically be worth half of its previous value at best. Next, look along the rest of the stick for cracks. It is unlikely that you will find cracks here unless the bow has been hit repeatedly along the stick or has had some other sort of forceful impact. Finally, check the frog and the area around it. The most likely cause cracking in this part of the bow is, again, due to blunt force trauma or, even more likely, over tightening the bow.
An Important Precaution:
If the screw becomes difficult to turn, do not keep turning it. This is especially important if it has recently been rehaired. If the hair is too long it is tempting to keep turning the screw to make it the right tension. But, once the eyelet has run out of space inside the screw mortise, you will be placing extreme amounts of tension on some more delicate pieces of wood, potentially ruining the bow by cracking the stick or by cracking the frog in half.

Bow Care... It is all too easy to lose one's bow because of not taking good care of it. Here are four "MUSTS" for taking care of the bow! Always loosen the bow before you put it in the case. The bow stick must rest from all of the tension that is created when the [...]
Why String Instruments Are Sensitive To Weather It is inevitable. Your wooden instrument has gone through a lot of change this winter. Wood is a hygroscopic material, meaning that it absorbs water from the air. This water is stored in the wood pores and is called free water because it can be [...]
1. Purchase quality strings. Just like tires, air filters, and shoes, there are strings that are made well and ones that aren't. When it comes to instruments, at least, much that is dirt cheap is more likely made for a quick buck than a satisfying (or even functional) customer experience. Talk with [...]
Not every cello has a wolf tone, but if yours does you know how annoying it can be. A wolf tone is an acoustical phenomenon which causes an oscillating sound that is similar to the howl of an animal. A wolf tone usually occurs on the D string when playing in first position. Luckily, there [...]
For many of our customers who are new to the violin, purchasing their first set of strings can be a bit of a shock! Because of the materials used to create consistent quality, the skilled labor, and the specialized machines that it takes to manufacture these small components, they are much more expensive than might [...]
In all cases where students are taking private lessons, do not purchase a new set of strings without consulting your teacher. In many cases, your private teacher will have specific preferences. Here is a sample of four of the many brands that we sell at KC Strings. If you have questions about any other brands [...]
All strings have a life span. This is because the acidity of the sweat in our hands begins breaking down the metal soon after we start using them. This break down affects the sound, which is dependent on the physical features of the string and it will also, eventually, lead to unravelling. This process [...]
1.) Have a dry or slightly damp cotton cloth. Over time, rosin will build up on the strings and the body of the instrument. Old T-Shirts, Socks, and Wash Cloths are sufficient. This should be routinely done to the instrument and bow. 2.) If this does not do the trick on the body [...]
If you’ve begun to notice a buzzing sound while bowing or plucking one or more of your strings, your instrument might be in need of a sound post adjustment. Situated inside the instrument, the sound post makes contact with both the front and backplates, transferring vibrations between them and facilitating resonance. Because the sound post [...]
