    Comatose gave an example of where skewling ... er, schooling ... might open up possibilities not otherwise seen. And even with hands-on techniques it is always just barely possible that a professor...

    A good word, but it may cut both ways. I would say a key issue is having both the desire and the means to become aware of what you don't know. Unfortunately, not knowing what / that you don't know...

    Me too. Can you even buy a car or truck in the US with a manual transmission anymore? (Other than, maybe, a sports car?)

    I know the focus is probably on first automation of machine tools ... but if I recall correctly, the first automation that really made a huge impact on employment and productivity was the Jacquard...

    In this situation, I would adopt a "take it or leave it" attitude, at least at the front end. To the school: either I'm insured against liability, or I will not teach the class. Your choice.

    g-coder's pictures brought back memories! I grew up in the PI in the 60's and 70's. Every house in Manila had a wall around it with glass embedded in the top, and bars on every window. I don't recall...

    I think we may be mixing up different requirements for teaching in a high school setting vs. in a college (community, technical, or university) setting.

    So let's get creative - as kustomizingkid said above, the idea of worker safety is a good one. Compare the working conditions in some third world countries, such as "just weld with your eyes shut"...

    Teaching is its own art/skill/talent; someone who is an expert in any field may or may not be a good teacher, and a superb teacher may or may not be an expert in the field (though it helps).

    IMHO,...

    EPA, I think we are largely in agreement! Government assistance is a catch-22 - it really does make it possible for some to go to college, some who will benefit from college and excel, who otherwise...

    That's interesting - I've never observed the lifting of the brushes, but then again, I haven't specifically looked for it. I'll have to take a closer peek at one of my R-I motors as I start it up!

    neilho, with this type of motor you can change its rotation by changing the position (angle) of the repulsion ring. It is possible that yours has gotten shifted into an intermediate position where it...

    Yes! This was my first thought; either a chip, or an incorrectly ground morse taper.
