With cane or hardwood shoots I generally make a single saw cut about 3/4" long(depending on point). Then I open the cut with a thin bladed knife and sandpaper(folded and refolded to increase thickness) until the stone point fits and is fairly straight. Then I drip hot pitch glue into the slot, warm up the point and bed it in the warm pitch glue. I spin check and adjust as needed. If it doesn't spin true heat the head a bit and readjust it and spin test...until it is true.
While the pitch glue is still warm I chew sinew until soft and wrap around and below the head. When the sinew is dry I spin test again. If all is good Seal the sinew...if not, reheat the head a bit, re-adjust, spin test, etc.
