String notches on my new bow?

[buckeyebowhunter]

I bought a bow off one of my friends that lives down the road from my house. The string that was on it was pretty old and frayed. And a few days ago I was shooting it and it broke at the loop. I didn't think much of it at the time but I bought a new string and have shot it for about a week now and the loops are already fraying. What could I do or have done to fix the string notches on this bow, because I dont want to destroy a lot of strings or my bow. Any info will be much aprreciated.

Drag a cotton ball in your string grove you will find the problem. you can roll up some 600 Grit sand paper. roll it up about the  size of your string groves and lightly sand it try the cotton ball one more time replace the string good to go.

Smooth the string grooves. But like SOS said: Post a picture or two of the grooves, so more info/advice can be made available.

Here's a couple of pics guys hard to get a good image that close with my camera but any more info would be great.

Sand the grooves.  Where the string comes down from the groove to the belly side make sure their is a arch going down to the belly side.  The smoother the arch the less friction at that point to wear the string by friction.

Here is what I mean

Sidebuster, what your saying is the string groove angle is a bit severe, so a little sanding should do the job? Is it alright to sand the fiberglass and the laminates?

[sidebuster]

Buckeybowhunter Absolutely, you can sand the fibergalss.  Make the arc like I showed on the pic so the string does not come to an abrupt edge in order to avoid wear and tear. Also make sure that the grooves or even from one side of the limb to the other side.  If one groove is higher than the other side this will cause wear plus bad shooting.

Thanks a lot sidebuster. -Robert.

ooh. Blurry pics. But they are clear enough to see that the nock grooves have squared edges where the string passes over both the back and the belly of the bow...and squared edges in those places are what you do not want. Sidebuster is correct: Put some arc into those places where the string passes over. It's ok for the grooves to be cut a little more into the belly of the bow.

After you smooth out those squared edges, touch-up the finish on the bow tips to help prevent splintering and/or separation. If the bow didn't have any finish to start with, then finish it. A good urethane finish should do it; just put some on the handle first (a **non-working** area), to make sure it won't muck up the bow...
