He states he has flux in the top(crown race seat end) of the crown(points to it) but not where the blades are inserted, no flux is visible on the blades in the insertion area before he applies it externally, it appears there is none in the insertion area, maybe I'm wrong though.
Yes he's using a rosebud, not sure what difference that makes in the brazing sequence, just up to temp quicker.
