TIK, formerly The Imperator Knight, makes long-form videos about lesser know WW2 battles. The early actions in the North African Campaign are exciting. I have one of his documentary playlists embedded below.
Mustie1 does videos of small engine repair. Most of his videos start with something simple that someone overlooked with the “dead” engine. He fixes that and usually cleans the engine as well.
Here are three videos where he fixed a forklift that someone abandoned because two previous mechanics wouldn’t follow their troubleshooting workflow to the end.
I have watched Mauler’s videos analyzing Star Wars: The Force Awakens. I recommend his detail-oriented and rational critique.
