Some fun old educational videos about complex mechanisms

Post by D.Olivaw » Thu Jan 24, 2013 2:54 pm

Like everyone here, I share an interest in a very particular type of complex technological entity; a natural sexual extension of my interest in all things tech-related, I suppose. I have a special soft spot for complex mechanical systems like engines, timepieces, and mechanical calculators (this http://bit.ly/3vx7bq is almost pornographic from my perspective :lovestruck:).

Anyway, I've found a few old instructional videos that use larger-than-life models to get across the operating principles of two of my favorite sets of mechanical devices. I'm particularly fond of the model approach to teaching these subjects, as it shows you the operation of a complex system in real time; something no amount of pictures can do. I tend to think it even has a bit of an edge over CGI models.

This one from the Hamilton Watch Co. explains the inner workings of a mechanical watch (perhaps of interest to our clockwork enthusiasts?)

This one from the Army Signal Corps (1945) explains the basic mechanisms of single-action firearms:

While this (part II of the above) adds to the model in order to explain the three types of automatic firearm actions:

Those latter two are by far the most easily comprehensible explanations of firearms actions I've ever seen; despite long familiarity even I learned a thing or two.

are good to their brothers:
they don’t want to mend
their own ways, but each other's"
