Lovely job. Looking at your forth image I believe the medullary rays visible on the end grain indicate that this is oak and not ash.

Hi morten_1
In what direction is the grain running in the fine teeth part of the comb? It appears that it may be at 90 degrees to the to the direction of the teeth. If that is the case, that could be the cause of the teeth breaking.
