dude, I know the wood piles you have used, and created for your fireplace.. I have tons of wood, unfortunately not all the types i want, but just had a huge cherry tree fall prey to our Wood boring interlopers..
Get the saw running, sharpen it well, and put good big chip cutting grinds on it.. dump the bar oil, rinse well with denatured alcohol, and fill it with Wesson oil, run it a while, then dump and refill with fresh food grade oil, and proceed to cut 1" thick slabs of cherry,oak, or other flavor wood limbs, and have a tarp to catch all the chips from the blade.. 15 minutes will net you a huge bag of chips, and slabs that can be minced into 1" blocks with a hatchet, and water soaked, for smoking.. I take all the saw dust/chippings, and throw them in a big trashcan with clean water, in the sun, stirring them daily for like 3 or 4 days, and pour off the water, (any oils float to the top, you can rinse and repeat if desired..), then dump that on a tarp in the sun to dry.. rolling it daily, to make sure it's totally dried, like a week or so, and bag it in a burlap sack,(or for or five) and hang it(them).. so it (they) won't mold.. and use that re-wet at use time, for my smoking adders..
free man, and very enjoyable. mmmm mmmm good stuff Maynard....
Living where I live, really rich people throw away stuff, at a whim.. I slammed my brakes on this past year, when I saw the most "majestic" (angels were singing 'AHHHHHHHHH") huge cast aluminum grill, a MONSTER.. that had to cost like $2k.. flipped it into the truck bed, (thing weighs like 200#)and even tho the steel "burner diffuser covers" were rotted, the complete thing still worked.. porcelain covered cast steel grill plates up top, everything all intact, other than the "grease dripper shields' over the burners..
It's in the process of having my "external smoke box" added right now, and when finished next week, will be the King of smoker grills..
yes, I am a garbage picker, and proud of it.. mmmmmmm smokey meats.. and the deer keep taunting me.. at my door.. mmmmmm
