About the tool post.... could it not be that we are seeing it in it's loosened position.... that he simply backed the tool out and turned the post so he would have more clearance for the drill chuck...... after drilling he will bring the tool post back to position and pull the lever back to lock it....? I know my tool post is often in my way when drilling tiny parts..... that is one reason I like my Taig lathe... I can remove the whole carriage in seconds.
