very interesting.
there is a chance the segment will crack .
there are ways around this ,

etc.
you then have to decide for your self if PEG treated wood is safe to use for a cutting board.
Id use PEG , then dry , then ' profesionally ' slice into 2 4 " rounds.
then sand , etc until stable. you can then treat the surfaces w an oil that polymerizes.
P.S. leave the bark on . it may decided to come off later , or not, depending on the time of the season
the wood was cut. it should stay on as you cut the wood recently , while the tree was growing.
if you take it off , you cant put it back on . if it comes off later on its own , is a different matter.
I have a cherry bookmatched cutting board I made ' by hand ' from cherry wood rescued
from my wood pile . its so beautiful , I just hung it up to admire it rather than use it.
after sanding and finishing ( no PEG , as it came from a cure log ) its a joy to see.
Ill post a pic here as soon as I find it , as things are jumbled up here due to some over the winter
remodleing.
