I watched the videos again and again and again, I moved it to A-3 this time because I think that is more of what I'm going for, the only thing that I'm confused about that he doesn't explain at all, is I didn't have to twist the top to get the pointed piece to line up against the right side of the rubber foot, he doesn't explain which foot it has to be against. I marked it at the beginning aligned with a specific one and it lined up again with it, i didn't have to twist it. should i go to the next boot anyway?
