Rick, I did notice! That was one of the things I like, and would be unable to do on my own. I'm actually certified to teach mid-level & intermediate math - basically 5-8th grade, up to intro to algebra, and I couldn't do what you've done. Most of my math-teaching experience (about 2 years, total) is in special education classes, for 1-6grades. I subbed recently in a Survey for College Prep Math class for a month & a half, and most of the kids, even those having trouble, were doing better at the math than I was. Mostly I showed them how to approach a problem, and to keep practicing until you got it, or the regular teacher came back... We were putting checkmarks on the board every time a student caught me making a mistake. Sometimes they were intentional, to check if people were paying attention, but mostly they were real mistakes.
As for what kinds of tools & techniques, on top of your screw holder tool, how about cutting tapers (preferably without off-setting the tailstock), Making milling cutters & milling cutter holders, and that sor of thing. As I said in a previous post, I've got the lathe, some cutting bits, and a 4-jaw chuck. Also some measuring gear, dial indicator & dial test indicator, cheap micrometers, 1 3/8" end mill with half-inch shank, and a MT3taper holder. I've also got the Atlas MF, and some tooling for it, once I get it working. Like I said, everything you've written has been interesting and useful to me; just keep on keeping on!
