Splicing manual for logging
« on: January 11, 2019, 07:19:47 AM »
From the mighty forests of British Columbia, here's a splicing manual that's specific to the logging industry.

And if you're interested in the cable yarding systems that the splicing manual refers to, here's the book on that:

Interesting to see another case of parochial knots
naming :: the logging book calls the sheet bends
(sng./dbl) "cat's paw" (single/double) !?

I wonder how this misnomer got traction?  One might
think that the normally understood version of the
cat's paw --i.e., opposed lobes of a halved bight
turned in mirror rotation to each others, making
a multi-twisted, two-eyed structure-- was more like
what workers with wire rope actually used?!

I'm reminded that utility-pole support lines have
eyes that are distinct pieces from the galvanized
steel line, and are attached to that line --being
properly/specially sized-- simply by wrapping them
around it (the eye being of *open* wire halves that
fit perfectly around the guy-line wire); it surprises
me that this structure has such friction to hold,
but obviously it does.


Thanks,
