Boy, am I tired..but still up and amped from the day. We did four jobs before this biggie, which we didnt start till 3:45...a 85-90 foot 2 foot dbh hemlock, fallen into a 155-175 foot huge fir. Hemlock below, on a slope leading up to a fence, then a second story deck with railing,through which the fir was growing.
Ian set a line at 55 feet, and footlocked the tail, then worked up and set the 7/8 sling and big block, through which we ran the new D/S Compsite double braid line with Spectra core. 18,800 lb minimum tensile, and 2% stretch at 40% of load.
Travis and I attached the GRCS to the fir. Ian set his lifeline at 85-90 or so feet. (There was still a good 70-90 feet of fir above him!) Then he set a lifeline for me and tossed it down, tieing it off, so I set my Vt in single line mode. I started up the base of the ivy covered hemlock, while Ian worked it from the top, with a handsaw. He even topped it at 4 inches leaving it barely lodged in the fir. We now had it tied off with the GRCS.
