After high school I went to work at a machine shop as a draftsman, 4 yr apprenticeship. As part of the apprenticeship I spent a little over 1 year working in the machine shop, got to run the common tools like drill press, bandsaw, but I also learned (basics) how to use a lathe and mill. The coolest thing was I got to actually make some of the parts I drew. 95% of the jobs we got were from NASA, back in the 70s they had a blank check and could just about spend as much as the pleased. Never did learn how to weld, but I did learn how to solder when I went thru my 2nd apprenticeship at Norfolk Naval Shipyard. Both jobs have been a big help in life/hobbies.
I have a mini-lathe (hardly ever use it now) and always wanted a mini-mill but never got one. Now I don't really need one.
