I am not sure if you are into machining, but this guy on YT is very good. A great example of the engineering talent you speak of.
This guy is a self employed machinist working out of his garage. But it's not a "garage shop".
What he makes and the care and precision with which he works is amazing.
His resume when he got out in the workforce what a hand built helicopter rotor assembly he made on a manual knee mill.
