I have several larger pieces of Cherry burl (2' diameter each) that have the bark still intact. These pieces have been drying for several years.
My intent is to cut them into blanks and cast with a resin into a hybrid blank. Because of this, I'd like to only remove the bark and leave the contours of the live edge intact. I also have the advantage where I do not need the full burl intact as a large piece (if it's easier to cut first and remove the bark from smaller pieces).
I've read in several places that a pressure washer can be used for this purpose, but my concerns are safety and risk of the wood cracking due to being introduced to moisture and drying again after years of being dry.
