diamond chainsaws

[Ken Barnes <barnestrav@zzzzzzzzz>]

I have used a diamond chain saw, although not extensively.  I found
that they did not work like wood chain saws.  You could not set it on
the top of a stone and cut through like you would a wood saw.  Instead,
you had to plunge the tip into the stone and then pry upward or
downward to extend the cut.  It was VERY difficult to cut a flat
surface on a granite boulder, although I think I would have improved my
skills over time.

Given my choice of how to create a flat surface on a granite boulder, I
would use a big bridge saw (if I had it), or feathers/wedge and an
angle grinder with diamond blade.  For creating a "step" in granite, I
would pick a bridge saw first, diamond wire saw second, and then it
would be a toss-up between a chain saw or angle grinder with
flush-mount saw.  I know that I could not create a clean step on my
first try, but maybe on my third or fourth try I would get it.
