Hi Ian..just a thought regarding any tools used when adjusting the secondary or anything inside the tube..please secure a cord or shoelace into the handle or around the tool itself and wrap it around your wrist..even though the tube is horizontal when you're working on it..it only takes some applied force or someone knocking the tube to send something horrible towards the primary..
