Floating ideas and looking for tips. Getting into smoking food and realizing 2 lbs of chips cost from $5 to $10 depending on species and brands. I'm a tightwad and want another option. A guy I know has a wood chipper that I could use. A-chips out of this should work, right? B-does it have to be seasoned before chipping (I'm thinking green and stored would be prone to fungal growth)? C-if splitting rounds or splits down to fit in chipper, 4" or less, should the only wood used for smoking be the heart wood and not sap wood/bark. D-anyone ever smoked with ash wood chips? E-how good will maple flavor be if using a maple variety other than sugar maple, like silver-red-amur?
