The secret to winding that coil spring (3:48 in the video) is clamping it down with your free thumb, which I didn't bother doing for fifteen tries or so because...well, because I only learn things by banging my head against a wall hard and long enough until the concept sinks in. Or until it hurts so much that I have to stop. I was swearing loud enough to disturb the neighbours, probably, so I went back and watched the video again for clues. I finally got the hint from that large thumb that intrudes into the picture. It worked flawlessly the first try.

I would now like people to pay me an annual six-figure income to overhaul shifters five days a week with a month's holiday off in July to go to France. I would like to sit at a bench and do this kind of work at my leisure, but for a lot of money. I wonder if there are any openings in a shop somewhere for a guy like me?
