I put off dividing it last year, but it's a must do upcoming project in a month or so. In preparation, I sliced a dozen 12-14w x 1.5-2 inch thick slabs from a large mesquite tree trunk, stained and have sealed them with a polyurethane to for moisture protection. Drill some holes for the tie downs and mount a hook to hang it, and be good to go.
Will take pictures of the process as I "learn" from drdawgs advice and will post the link here to the whole story and pics in a separate article when finished.
