A ?? for other Fairbanks wood burners (or others in fairly dry climates): Do you really NEED to split birch if it is cut to 40" lengths and stacked/covered w/ a tarp? It seems that the stuff I cut last year and stacked in lengths up to 4' is all cracked and dry looking. A friend said you don't need to split birch unless it is over 12 to 14" in diam. I'd sure like to avoid building a log splitter, and I understand that wood dries 90% through the ends (xylem and phloem just do their thing, cut down or not). My wood will be sitting for at least 2 yrs before I burn it, and burning rounds in the boiler will be no problemo..... if it is dry. What about the aspen that I have? Is it a lot wetter, so that it needs splitting? Thanks. I have no experience w/ wood and don't want the several chords I have stacked to all rot from the inside out. Thanks. john
