Didn't have a real good machine shop class in high school but it was mandatory in engineering school. We covered enough that you would know what process might be needed to make the part you designed/needed. That was covered in the lecture. Then the lab part involved actually using a broach (didn't even know that was the thing), mill, lathe, planer, casting aluminum, welding (gas and stick), stamping, shearing, etc
I use something from that class daily at work or at home. It makes me wish I had a machine shop at home.
