    Sounded thin. You made me check. My eraser shield, probably from the
    '60s, seems to be .0051" . (I have no way to measure just the areas
    close to my most frequent mistakes -- maybe a bit thinner.) Another case
    of the cheapening of modern products?

    Hmm. Just noticed there is a very slight cylindrical curve to the
    device. I was never instructed about that, or forgot, seems the proper
    application would be convex down?
     
  2. Maybe they didn't have the technology to make it that thin back then?
    ;-)
    Dunno, I don't recall any formal training in using a shield. I barely
    remember using a drafting table with the arm etc. in high school.

    I don't think the curve was intentional. I think it was a result of
    punching all of those fancy shaped holes. My recollection is the concave
    side has all sorts of sharp burrs that will eat your eraser PDQ. I always
    used mine with the concave side down.

  4. Oh, that's what he meant. Yes, one side is rounded a tiny bit and the
    other has a sharp edge.

    Bob pease talked about the sources for Teledeltos paper:
    http://www.elecdesign.com/Articles/Index.cfm?AD=1&ArticleID=2323
    His links didn't work for me, but the modern equivalents weren't
    hard to find. Sensitised Coatings, http://www.senco.co.uk and
    Pasco, http://www.pasco.com/products/groups/70-482-1.html

    I always bent mine concave side down. Makes it easier to pick up.

    When we moved out here we briefly had an apartment and thus cable TV.
    Then I discovered that there was one Episode of Gilligan's Island every
    morning at 6:30am or so. My wife said that I've got to be kidding...

    Thanks! But it looks like Pasco has that weird habit of not disclosing a
    price until you key in your personal info, including school. So I guess
    it's academia only?
     
  9. Great show. Powering the radio from coconuts. Shame I was outbid on
    eBay for lunch with Mary Anne (benefiting charity, of course, she's
    such a goody-goody).
