For those who like to watch YouTube, you'll note that there's not a lot of Norton coverage. But there is a guy in Canada who has documented a Commando rebuild from the beginning and he's done over 100 videos in the series. His channel is called Motor Oil & Beer. He' is not a Norton expert, he makes mistakes, he finds ways to do things without all the right tools, he innovates, he shows it all, and he appreciates comments from viewers. I enjoy watching his videos. Since Google took over YouTube, it has gotten progressively harder for people like him to get compensated for the time and expense it takes to provide good content. The latest change is that besides numbers of views and amount of watch time, he must have at least 1000 subscribers. If you enjoy watching YouTube, have a look and consider subscribing to his channel.
