there's some truth to band dust being too fine, but it's not written in stone for sure,, walnut is surely bound for the where ever they take it, most mills that saw big time walnut,, dry their own, so all the waste goes into the furnaces that fuel the boiler. Cedar dust is bad for fowl, so that's out, FFA that shows swine use it for shows and pre shows, it may be for nothing more than floor dry, not sure, I know I had one young lad come by and load up several times, and another couple that raised goats, believe that? I did keep the oak an pine separate mainly for my own uses. pine breaks down a bit quicker than oak, plus pine has a bit higher ph from the get go. My place in Texas county Mo. Ozark plateau, upper end of the Jacks Fork, and National scenic riverways, not much black dirt here, plenty of rocks, we are between the Eleven Point and Jacks fork, Eleven points south about 8 miles, the upper end of it, Jacks fork bout a mile, use to be lots of turkeys and chicken farms, not much any more, cattle farms, some dairy, and homesteads, no need to mention sawmills, dime a dozen on every corner, pretty much. My wife says I ought to quit looking at these sawmill sites, saying its' causing me too much torture,, I'm thinking about putting together a CSM, just a small one, the alaskan design or the panther one looks easy enough, other than the work it self, a little care, and I think it could happen.
