This page of the Ukishima Diary has pictures about midway
down the page, which will take several moments to loadl,
of earthquake proof pinning of a tall work. Eight inch
and a quarter of so pins embedded what looks like eighteen
inches or so. I was amazed that they hand drilled the
holes by eye, there is a photo of them doing so. How they
could get eight long rods to line up at at such great
length with an allowance of less than zero margin of error
has boggled my imagination. I have been mystified as to
how they managed it, but today revisiting the sight I have
a guess that they drilled overly large holes and then set
the rods in with epoxy and templates to space and allign
them correctly? Engineers have most definitely set
specifications.
