Lee...just seal the sapwood,ends,and several inches along the belly and sides from the ends. I debarked,sealed(shellac),and roughed down a couple staves of my yew overhaul and there fine so far. They've moved some due to the rapid moisture loss. So I learned yew needs to season slow,and the slower the better. So now im leaving the bark on the rest of it and wait the long wait for it. Its the right thing to do. Try to put your staves in a cool high Rh environment for the first several to 6 months before moving them in a warmer drier environment.
