I love engineerguy's videos, but to me it seems he could have picked a more interesting subject. I find it hard to imagine a person that hasn't taken one apart to see how it works.

Ah well, quality production no matter the subject.

"I" think they handled this material excellently, however pedantic. Myself, I am in the process of compiling such research for a Vlogcast of my own which resides in a similar vein, to be called "Wicked Lost Technology". I plan to look at inventions that were once cutting edge, yet today are all but forgotten. These item still offer great inspiration for us today from a mechanical perspective and should not be forgotten.

The thoroughness of the Engineeringguy in this video should not be overlooked. He/they get(s) my applaud!
