I've not made a warbow period but its on my list
and i have a honeysuckle stave i'm going to try and make into one.
as far as your stave if you cut it in the winter(depending on how cold it gets were you are) you should be good just seal the ends, pretty standard procedure. and if you can leave the bark on, it peals off pretty easily even after its dry.
if you cut it in the spring/summer you need to pick your belly side and rough it out otherwise it will check exactly where you don't want it too
