In the early 1970's my GF at the time and I went to adult night school at a high school here in Sacramento. She took wood shop and I took metal shop. Wednesday nights from 6-9:00 pm. $20 per semester. Both classes were project based. You could make anything you wanted, use any of the tools you knew how to use, if not, ask the teacher or one of the old hands there for instruction. Help yourself to anything in the scrap bins, otherwise buy materials at their cost, by the inch, foot, or whatever. Welding rod and gases, tooling, solvents, safety glasses, gloves, and everything else was included for the $20. Nicely equipped shops. Great teachers. People built boat trailers, one guy built a 18" band saw, I helped him cast the brass pulleys, one fellow was making a run of carburetors for WWI LeRhone rotary aircraft engines. We attended those shop classes for years, and it also got me started in metalworking and into the truck and heavy equipment trade as a parts man. I would still be going there if they had not shut it down... ;-(
