Chicago, The Complete Rigger's Apprentice by Brian Toss has a few pages with diagrams on "Coiling and Stowing." The balentine is not covered. For the figure-eight coil he says "It is always made on the deck rather than in the hand." The Crusing Handbook by Nigel Calder does show a figure-eight coil made in the hand, but not by using a winch or post as a third hand.
Animated Knots by Grog also shows a diagram of completed Figure 8 coil, but with no description of making one.
