Mike Darlow's website was included in the article - and of
course I forgot to include it in my original post. Here it
is for those who wish to check out his qualifications.

As is so often the case there are opposing opinions of
someone else's analysis and conclusions. I was trained
in Chem E so the statics based analysis makes sense
to me in terms of the mechanics. I'm afraid that a
dynamics analysis would be a bit complicated to put
in a four or five page article.

I suspect that many turners learn to compensate
for a tools shortcomings, find a few they like and
stick with them, often defending their choices to
the death.

There are two of his articles on his site that I
found interesting - both rang some bells.
