I enjoy your pics and descriptions of what your doing. Coming from 4 generations of tree work, dating back before chainsaws, I “Understand” what you are saying. We did residential work with a lot of rigging over multi million dollar homes. Often removing one big ornamental to make a drop spot to chunk down 18” chunks, because we couldn’t dent the yard felling the log. That’s a dying skill. Now a days they say sorry no other way to do it, and just crush stuff up. One time my Dad went to a factory in Baltimore that made 8’X8’ burlap sheets, and bought a whole bale of them to cover the yard. The customer didn’t want any saw dust in the grass. I wish Dad had of taken more pics back then. I have one of Dads 3‘ hand saws hanging on the wall. People don’t believe that in our lifetime they used those to take down a tree. When I was a kid we still didn’t have small climbing saws, so all of our climbers had big hand saws. It was amazing to see how fast they could make a cut with hand saws.
Anyway, what I was going to say is, I’d feel pretty comfortable sharing techniques here. Most of these guys have multiple saws and know what a sharp saw is. Don’t do it on the Homeowner Helpers forum. You tell some one to make an open face cut and a fast back cut. You and I are using a 100CC saw with a 36” bar and razor sharp chain. The homeowner is using a 16” dull box store saw. Our face cut comes out in a perfect wedge. Theirs comes out in 3 pieces with multiple angles. Our fast back cut takes seconds, and is one cut. Theirs, the bar won’t make it through the cut, they are see sawing with their dull saw. You can never assume there equipment is in the condition ours is. My advice on that forum is, call a pro, live another day.
If anyone here sounds like the homeowner, that’s my back door way of saying don’t do what you think the pro is doing, it is dangerous.
