I need to have a freshly downed oak tree stump ground down. Can I dry and use this wood chip for smoking?
X2 they make food grade bar oil, have even seen some use veg oil. On the other hand, they also make bar oil with some sort of enzyme that will speed up the natural rotting of the stump so removal is not required. I don't think that stuff would be too good for ya. Be carefulBe careful if using a chainsaw to grind the stump as you are likely to contaminate the chips with chain lubricating oil. This will not taste good!
When using the chainsaw simply to cut logs the amount of oil on the wood will be minimal, however if you are collecting the chips produced by the saw then depending on the saw the contamination will probably be much higher
