Very nice. I thought maybe they were going to some schools or
something. They look like good demonstration pieces.


Funny you should mention that, I used that book to create a series of
projects for a manufacturing tech. class back in 2001. They were great to
teach a variety of machine processes, including the requirement that at
least on operation had to be done with CNC. (they could even drill holes
with the software we had...sorry couldn't resist)

The mechanisms in the book were great for teaching manufacturing and the
finished mechanisms, they were taken by teachers to use as teaching aids.

Your experience probably agrees with that I've heard from many teachers,
that a physical example of what's being taught is a tremendous help both in
explaining the lesson, and, even more importantly, cementing it in the
students' memories. That's why I've built demonstration pieces for several
of my son's classes when he was in school. The tin-can electric motor was a
particular winner.

It's also a probable reason that physics was my best subject in high school,
and why I remember so much of it. We built equipment to demonstrate
practically everything. I even built a ruby-rod laser that was pumped with a
No. 25 photographic flash bulb in an elliptical reflector.
