I separate by species in my individual stacks and label the stack with species, month and year when stacked. It's like vintage wine. I also have bins for the stuff that is cut too short to stack (see my post regarding hand splitting elm) and miscellaneous wood that wouldn't fill up a proper stack. Then there is the oak uglies bin.
I put my knots/crotches/uglies on the top layer or two of my stacks. They can't do any harm to the stability of my stacks up there.
We just burn them. Don't cut them off really but do try to cut the limbs flush to the trunk so as not to get too ugly. Then just split it and stack it.
After trying to stack my wood as you all do iv decided FREE wood doesn't stack neatly . But I have to collect what's going , so made the best of it
Started at three feet at the base but tapered it up to two feet on top , trying to give myself as big a gap as I could between the fence and wood . Ended up with a ten inch gap at the top and six inch at the bottom .
I mix all my wood. Mostly oak, some maple, cherry and birch. I just burn the oldest first. My OWB needs to be loaded once every 24 hours. If it's not all that cold I'll only fill it part way.
I set my electric splitter on the tailgate of my pickup. Then I am lifting rounds off the ground, splitting, and throwing them into the truck bed for moving to the stack, or I am pulling rounds off of the truck bed, splitting, and stacking. Depends on context.
Those little electric splitters do a pretty good job. I had one the other day that was rather stubborn but I tried different ways and finally managed to get it split. I have found that sometimes it helps to reduce the bite of the wedge by raising the front a bit with a piece of wood.
