Here are some photos of how I did the horn inlay to repair the dry checks cracks in the yew brush nock build up.
Here you see the drying check/crack in the yew. This one did not present itself until I had repaired the major ones in the brush nock with the blonde horn "runners" on the top of the brush nock. This pattern of repairing one crack, and a new one appears happened several times...resulting in the three different horn inlays in the brush nock valley. The cracks only presented themselves when the tip of the bow was grasped and unnaturally bent backwards to pry open the weak dry check.
I hot-glued a piece of blonde horn onto a 5/16" arrow shaft. with a flat spot carved in.

Excavating a half round for glueing the horn in.
After ensuring a tight fit, both surfaces are scored with a knife tip and glued up with super glue.
Heat is used to release hot-melt glue bond between the wood shaft and the horn.
