I was intent on filing the tips on a new recurve build this morning and didn't notice until it was too late that I filed through the Fiberglass Lamination under the wood overlays.
Here are a couple of pictures to show the issue:
Without string:
My first thought was that this is shot and will split out on a 55#-60# bow. That would mandate piking and recutting the limbtips to resolve the problem. But, then I looked back on my all wood bow builds and know that as long as I don't violate the back fibers a B50 string will not harm the wood in any way. There may be a small about of FG still there but the wood lam was not harmed.
So I am leaning on finishing it up the way it is and marking the bow specs for B50 only.
Another thought is to mix up a small amount of Smooth On and coat the groove with it and maybe a thin strip of fiberglass cloth to bond it all back together.
Any thoughts and suggestions will be appreciated.
