Adam Savage's Tested - cosplay, engineering challenges, interviews with makers
Project Farm - no nonsense tool/equipment tests
Bad Obsession Motorsport - two guys taking WAY too long building an old mini into a rally car
Primitive Technology - John Plant building cabins and clay tiles and basic iron smelting in the Australian woods. No talking at all, but turn on subtitles to find out what he's doing
Stuff I didn't see recommended:
James May's The Reassembled - Top Gear's Captain Slow putting things back together. Very ASMR
What's Next - the new name for Drive Tribe, the Top Gear guy's video channel. I love the series where they send their curmudgeonly producer on last minute international travel to shoot ad hoc travel shows
TASKMASTER - a British TV show where celebrities you've probably never seen before make their way creatively through challeneges
Taskmaster is so good. And it's basically all available to watch on YouTube. I finished all of the original seasons and started watching some of the spinoffs like Taskmaster NZ
