So far have roughed out about 10 bowls 6-10 inches diameter. I dulled two chainsaws slicing up the blanks. Wore out a brand new bandsaw blade cutting out the circles. The wood is wet and does not appear harder than average but it is rough on gouges. The first 2 or 3 passes the wood just peels out great. Then it doesn't cut so well. Feel the gouge edge and it is dull as a hammer. Lay it aside and get a sharp one out. Same story.
Maybe I should just turn discs instead of bowls then I could use it for grinding lawn mower blades.
