I scrounged up some fat wood out of pine stump’s yesterday, and I’m new at this stuff, sorting out what’s worthwhile and what just to throw away. My goal is pencil diameter pieces to supplement waxed twine. And because it fun. I use a ferro rod almost exclusively when I’m up in the woods. Here’s pictures of the wildly varying density. To test if it’s any good should I just try to light a small pile of scrapings with the ferro rod? Any other suggestions on sorting and processing this stuff, assuming I probably have a lot of lightly saturated wood to strip out? I cannot easily tell either what’s saturated with sap until the wood dries.
