So, after my first year in biz, I've managed to collect a couple of different logs in my wood pile that I have questions about burning in my fireplace: Black Locust (I know people who burn this in stoves and firepits, but remember something long ago about a noxious odor/gas for fireplaces)...
Sean & John id'ed the ones properly. Nutball's response is for the one in his locale, which are known to be smaller.
Some pics of a prune from earlier this week. Historically power lines had run in front of the tree and the pruning not always been sympathetic. We reduced it by a couple of meters overall (and a bit more in some bits to reshape it) turned out ok we think. think.
It went slowly over the day, we redid cribbing a couple times. I was surprised it kept sinking as it usually compacts the soil and stops. Sunk about a foot during the course of the day, we were working directly over it , the tree was at 70' over the house.
Btw @PCTREE , you really should make up some mats, they work far better and setup far faster. I know wood is outrageous right now, but most I've seen use 2x whatever stacked solid in at least 2 layers 90 degrees apart, with 1 inch plywood on each side, everything glued and nailed. Then nail ropes on for handles. Basically make a giant cribbing sandwich to spread the load, and set those up instead of cribbing with skids. If you build them round you can roll them, but square is easier to build and gives more area and is easy enough to move with a couple guys. I've seen bigger cranes where they actually use the crane to set them on tires first, then they level up with the outriggers. I'll see if i can find some pictures, it's the way to go man.
Kyle I used mats for a few years. 3x4'x4" oak. Over time we went away from them, as with the setup shown they just wouldn't work. Often times when setting up around houses you don't have the space to put them down . Im digging those white oak 3" x 12" planks we just milled, we have 3' and 5' and can be setup around bushes etc to distribute load
