Wife's cousin gave me a very large pecan tree,this thing is a good 40 inches at the base.The limbs that split off it are from 18 to 22 inches in diameter.I only cut one 20 inch limb off so far because the rest of the tree will fall on some of his crops.I cut this up to length and carried it home.Now I'm an old country boy and have split oak wood all my life by hand.Well I set a big old piece up on my splitting block and took a good swing with my splitting maul..Bam! nothing happened.I could hardly make the maul stick.This stuff is worse than sweet gum to split.I'm having to split a 3 or 4 inch thick piece off the side to get it split up.This is going to take a while.When I cut the rest of the tree down ,I'll rent a log splitter.But for now this old man will get a work out. When I finish I'll have enough pecan wood for the rest of my life time.But it will all be worth it when I start using it.I can taste that chicken now.
