I'm going to be taking down a 40' oak in the near future, which means I am going to have a fair number of limbs that are too large for my chipper/shredder but not big enough to bother stacking for firewood. I've already limbed the bottom 25 feet and have enough small stuff to last me a couple summers in the chimenea. If you're interested I can let you know when the big fella is coming down.
