By the way, I'm having fun in this class. It's at Lake Washington
Technical College, and they have a pretty serious machining program
there. Lots of students, two reasonably competent instructors, and
lots of machines in decent shape. They're teaching me tool & cutter
grinding and so far I've learned to sharpen the end teeth on end
mills and how to sharpen the end flutes of chucking reamers. It's
an evening program run 4 nights a week, with community college
pricing. It's located in Kirkland, Washington which is convenient
for me anyway!
For people who aren't nearby, let this one stand as an ongoing
endorsement of vocational school shop classes!
Grant, now that is good information! I will try it --- next time. If only
you could elucidate on a similar trick to remove broken taps!
BTW, speaking of center drills and cutter sharpening - have you ever tried
re-pointing a dull center drill on an ordinary drill sharpening set up?
