One solution may not be appropriate in all cases and it may need to be modified depending on the type and extent of the break. A backstrap is good if the crack does not go all the way through into the nut slot or headstock veneer. It the headstock veneer is compromised, a backstrap may not be enough. A break through a Gibson truss rod nut recess may be best repaired with splines. Some breaks go directly across the grain which may need multiple techniques, like the Epi I mentioned in a previous thread.

The last time I used splines I used short and small carbon fiber bars instead of the normal wood splines.

Barry, where did you get the cf bars? I’ve seen several sources for 18” or 24” lengths but wonder if someone sells them already cut into short lengths.

I just cut them from long bars that I use for neck reinforcement. I like 1/4" high by 0.093" wide bars from Dragon Plate.

Thanks Barry. Two more quick questions:
- Router bit - 3/32" ?
- What do you use for adhesive?
