I just cut my batch of hickory to season - I cut small diameter saplings or branches, approx. 2" to 3" in diameter and about an inch long with the chainsaw or with my miter saw. On the pieces that are 3" in diameter I'll split them once with a quick pop of the hatchet. I cut a milk crate full just last week. I'll soak the chunks in a bucket of water overnite before I use them to smoke. I make whole shoulder bar-b-q in my 30+ year old Weber grill - it will hold 2, 20 lb. shoulders. I start a good pile of charcoal in it, then spread that out and put a solid layer of the wet chunks on top. Check/work your fire about every 1 1/2 - 2 hours add hickory as needed. Shoulders are done in 6 to 8 hours, depending on how hot you keep your fire going - use a meat thermometer. You'll find that you'll still have charcoal left burning for some dogs or burgers even after 7 or 8 hours - seems the coals act as a catalyst and don't burn up like you would expect. Green hickory works just as well for smoking too, creates a little more resin but flavors nicely and gets/keeps you cooking when your seasoned stock is gone. By the way, a milk crate full will do me about 4 or 5 cookings as mentioned.
