I have been making my way through the Lapping film, try it thread (up to page 43) and have just watched the videos. Everything seems to work in the videos as I imagined it while reading, except for one thing. In the first video when setting the bevel, @Slash McCoy appears to be moving the razor back and forth on the film, rather than using edge leading strokes as he does in the rest of the video. Is this the correct way to raise a burr, or am I reading too much into this? I am planning on buying some film to try this, but want to make sure that I am doing it correctly when I do.
