fork call

[pete]

Forks, pipes, segments. These are, for me,

? three very similar things. The

fork is on the left hand side of the plate.
The pipes run overhead. BTW, I
liked the link you posted for pipes recently

I used to cut threads on pipes in a machine shop.

Hence, your attention to detail. I'm going bats trying to figure out how
the pipefitter did whatever he did above me. I wonder if I can describe it
abstractly. The node I observe first has order 4, the second order 3, the
third order three, the fourth order two, the fifth order two; the sixth may
either have order two or simply be called NULL . Every day, as I look, not
at a blueprint, but the actual installation, I call it impossible. Then I
tell myself I just Don't Get It (tm). joe
