I just got home from slashing for two days at slashers. Probably 40-60 trees if including little ones. Tons of challenging fun trying to thread the dead down between the live. Got to do a partial spin rolling one off another but cutting one side of the hinge, and another I cut the hinge clear off and let it spin off the right tree and then off the left. Little ones were the most hassle. Easiest to miss the lay (I missed a few small ones but only one of any size, end of the day, getting dark, didn’t matter, just general direction) and the littles would get stuck easy too.
First successful sizzy was overly successful, swung a little tree over 100° to the lean.
Small(er), straight trees, especially with an off-center center of gravity are the worst.
Gonna try to load your video.
Edit: In late 2021 I did a couple days out in Trinity for my lady's friends. Mostly firewood and cleanup from a contractor who did a pretty crappy job on a multi-acre, dense FLASH job. I thought it was all firewood, as the husband has been very sick the last few years.
He changed it up the last day and wanted me to fall some trees instead. A patch of six totally dead standing firs, 80-100' tall, all straight as arrows with no significant limb weight.
I took an early lunch to take extra time to size up the trees and planned where to put them.
60' away, 90* to the trees is a nice 3/4 ton truck that isn't running, a storage building, etc...so, some obstacles IF they went loose. Nice maples, alders, and oaks behind the group of trees that we didn't want smashed.
All the trunks were more sound than I had anticipated, which made life easier. 16-24" diameters.
I looked around the area at nearby stumps to see what may have been competing and verified the course of the sun (property is down in a hollow) to aid in my decision.
I cut the first one 90* downhill of where the others would go to avoid hitting their trash/recycling area. No sign of insect damage and straight, true grain.
Good signs.
Spent the rest of the afternoon putting the others on the ground and bucking into rounds for them. Everything went smooth because I took as many factors as possible into consideration.
