I studied mechanical engineering craft studies in the 1970's, thank you for posting this interesting video.
I was a full time college student in the early 1970s and these education programmes were part of the basic craft course I was on together with similar studies on other courses.
Thanks for another video showing how stuff can be protected.
Great video. I just wish I knew why galvanised surfaces are two different colours?!
Lord knows what those guys were breathing in during the production process. Yikes!
It’s like modern China conditions
