If you can spread the crack,
fill it full of urac and clamp you would be good to go.
Just to see if I could do it I started with this.
Didn't have enough wood for a handle so I added this.
Shaped down to this.
And sold the finished bow for $80 to raise money for an ailing friend who was $80 short of what he needed for a project.
The bow surfaced in an archery shop in Chattanooga years later. The guy who bought it sent me this picture to see if I could identify the bow.
So, you can get away with a crack that runs out through the fade if you have the right glue. The bow in the picture is bamboo backed which also helps it's structural integrety.
