I don't have a build along but I can tell you how I haft a point. I use pine pitch glue but others use epoxy or super glue or even TiteBond.
I taper the point end of the shaft and cut a slot in the end(I use a band saw). I usually line the point with the nock so it is mounted vertical.Then with a thin bladed knife and sand paper, I open the slot to fit the point. When I get a good fit I melt pitch glue in the slot and push a preheated(not hot) point into the slot and eyeball it from 4 sides to be sure everything lines up. When the glue cools I spin the arrow with the point on the palm of my hand to be sure everything lines up and the arrow spins true. If it doesn't, re-heat and adjust again. Once everything is lined up the sinew wrap comes. With some points the sinew goes around the shaft and point and on others, just around the shaft and a tang if the head has one. I usually don't use hide glue but chew the sinew until soft and wrap it. Your saliva and the sinew will make its own glue. After it is dry I apply a coat of pitch varnish, super glue or TiteBond to seal and waterproof. If the point becomes askew, you can re-heat the point and glue slightly and re-set it. Pat
