I use a Craftsman Scroll Saw, a small round file for cleaning up the cuts marks, and Copy the Depth, Width, etc. from a Favorite Plastic Nock. Then I wrap them with Either Dental Floss (Can Be Colored with a Sharpie Marker later),or Arty-Fishul-Sinew that can be had at the Hobby Lobby for Cheap.
As Long as the Cut is Perpendicular to the Shaft Grain, You shouldnt have any trouble. THEN, you can whip them on yer Shootin' Buds and say "Look What I Done!"
Good Luck to ya Buddy, You will do Fine!!
