Funny...just emptied steel Dust Deputy canister about a week ago, and rather than disconnect everything and try to get it out to the woods in my wheelchair, I cut the bottom of a Clorox bottle out and scooped it out by hand...and went down through layers from pre-Christmas:)
Very bottom was a lot of White Oak/Maple burl bark and wood, then Christmas exotics in a thin layer, then a bunch of Paper Birch bark and wet wood, and today may have thunderstorms, so decided to face at least one side of a few Black Walnut branches where each toolpath is about 3 minutes.
Almost as much bark as wood recently
More bark today...and if Anchorseal II test on Paper Birch today doesn't stain....then I can get into the 2 12-16" White Oak burls I need to cut with Japanese Log Saw, and I can get into those:)
This should be interesting Randall
