Loose frog?

Instruments: Frog issue?

From Michael Chang

I just bought a bow which fits perfectly with my violin last week, but today i noticed the frog is slightly loose. If I hold the stick and push the frog, it will move about a millimeter. Is this a major problem?

One milimeter is a big gap, I think, take it to an archetier, don`t try to fix is by yourself.

Hi Michael, I'm not understanding your inquiry about your bow. You say that when you "push the frog, it will move about a millimeter."

Are you referring to a rocking side-to-side of the frog on the stick? If so, then often simply tightening the eyelet (usually 1/2 turn) might take care of the problem. This is something that can often be done--with care--by a player.

If you are referring to a gap at the back of the frog where it is lifting off of the stick under the tension of the hair, then there might be wear on the eyelet or the screwholes. If this is the problem, then the bow should be taken to a bow specialist for an evaluation and repair.

I hope that this helps to steer you in the right direction of what might be happening with your bow. If you can clarify what you mean, and how the frog is moving, there might be better advice to come. I definitely second Luis's recommendation to get a bow expert to look at it for you. The movement of the frog might be something quite minor, or it could indicate a bigger problem.

 Thank you Josh, you quelled my anxiety :). It is merely the rocking side-to-side of the frog, and I will try turning the eyelet 1/2 a turn after I finish my calculus homework. Thanks again! :)

Michael, as you attempt to tighten the eyelet, be VERY careful not to damage the thin, fragile sides of the underslide. If you attempt to do this with a standard pair of pliers, you will likely hit the sides of the underslide, bending them out. I use a pair of parallel-jaw jeweler's pliers that I have ground down the nose so I can turn the eyelet without hitting the sides.

A method that some people use--but I'm not saying this as a recommendation--is to place the front of the bow screw into the eyelet hole and use the screw to turn the eyelet. This method can also cause damage if the screw threads scrape over the top of the underslide, leaving little tooth-marks in the silver. You can also bend the screw if the eyelet doesn't easily turn.
