These are some of my favorite channels - all are with checking out! Most share a common theme of how to's or projects. Enjoy!
Abom79 - https://www.youtube.com/user/Abom79
Very accomplished and newly working for himself machinist. Watching machinist videos can be hypnotic.
Andrew Camarata - https://www.youtube.com/channel/UCUujfNBK9uv3cIW-P5PX7vA
Operates an independent excavation business - all about hard work and fixing your own machines, and he built his own shipping container castle workshop thing!
Car Wizard - https://www.youtube.com/user/OmegaAutoService
Very mild mannered / calming approach to his videos, eclectic mix of cars in part because one of his best customers is Tyler Hoover of Hoovie's Garage (below) - and he's working on putting a diesel in a '69 Cadillac - it makes sense once you hear him out.
ChuckE2009 - https://www.youtube.com/user/ChuckE2009
Earlier content has lots and lots of welding how to and reviews, has evolved into workshop projects and tips videos as he's developed quite an addiction to buying derelict tractors with hopes of bringing them back to life.
Cleetus McFarland - https://www.youtube.com/user/GARRETTmitch
Pretty much just unadulterated fun as they constantly build and drag race their cars even faster and faster. Leroy the Savage! And they're working on building an El Camino jet car.
DEBOSS GARAGE - https://www.youtube.com/channel/UCLXV9vzJwgYOyGaZlD89VfA
Very diesel-centric shop, all about engine swapping and making any kind of project you want. Some really good maintenance and project content as well - and some shenanigans with engines for fun.
Hoovies Garage - https://www.youtube.com/channel/UCdEczn3MVkx_4PnMZ10MVFA
Tyler Hoover is an automotive journalist who focuses on buying pretty much, well everything really.
Mustie1 - https://www.youtube.com/user/mustie1
Small engine and VW wizard. All sorts of interesting projects as he makes some really neat builds from yard sale and flea market finds.
