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?

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.

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

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...

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).
