Arrowslinger,
You mount the head the same way as a stone point. I cut a slot with my bandsaw (you can do it by hand) to slide the tang of the point in. Then you'd epoxy and wrap (dental floss, sinew, etc) around the slot to bind everything together.
I once had had a compound shooter Robin hood a self nock that was wrapped the same way. The wrap kept the compound arrow from splitting my arrow. It only mushroomed the self nock. I was pretty impressed with the strength that wrap gave to the wood arrow...Doc
