The cambium layer is really thick on these staves, at least 1/4". I will use the edge of the cambium layer as a guide and slice off as much bark as I can with my bandsaw set and an angle so I don't get into the heart wood. I will follow up with a draw knife. After the staves cure a little I will finish up with a scraper.
I have plenty of bark on scrap and will try an experiment on bark removal with my pressure washer just to see what happens. I have de-barked dry stuff with it before but not not bow wood.
