How to thread a film projector

An instructional video made for school. About two minutes edited out of it. These projectors were installed in the 60s. Update: I think I was 17 at the time. I was a projectionist for 3 years, from 2008-2011. I also ran projectors occasionally at a drive-in, and they work basically the same way, but with different problems (like sunlight, being outdoors.) Film projection is a dying skill, so I'm glad it is being documented on YouTube.
