This 36" dbh fir near Puget Sound had the original trunk up to 80', where two 40' co-dominant tops were, until the recent windstorm.
The homeowner is a therapist who had to cancel patient appointments last week, and is booked m-w, so yesterday I rolled solo, wanting to finish the job and move on, without scheduling conflicts, and weather was very friendly, so make hay while the sun shines, especially in January in the PNWet.
I set off with a full tank in my 193t with a 14" b/c, wedge, three-strand rope in case I needed to rig any limbs or the top.
No rigging, climbed up for a small top 3.5"-4.5", wearing pole spurs.
Spar is down to 50-60'. I had a little gas left (I sharpened a few stores, but unfortunately didn't file the rakers, so slower cutting, less fuel 'mileage' than ideal.
70 minutes.
Power line (across asphalt driveway), cable line (orange ratchet strap reminding me of the alignment), power box and trees/ landscaping, below, partially protected with two sheets of plywood.
One narrow car parking lane below (I very much squeezed my dually in, going off the lane somewhat). Some available green space one two sides, also, for cutting and throwing into the holes around obstacles, without landing on my climb line or rigging line.
Chipping mostly onsite, and firewooding.
Someone asked for pics of bigger logs. I had to strip this just below the breakout for about 20-25', pop a 15-20' top, and chunk it down, with a not ideal chain on a 193t.
This is the barest amount of more cutting over a perfectly-executed double-cut Undercut-COG-w/ thin-hinge cut. No risk of the hinge not being cut perfectly, and rocking to one side. No room for logs to go off the target. I cut some extra wood out of the last log to stack on the face-cut, as I didn't get it 'faced-up (without hinge)' the right direction and woulda hit the big maple down below, and needed to direct it a bit, which worked out fine.
