i have the stave of a lifetime in my endeavour to build a bow, in my opinion. my question if this and it may have been addressed in another topic somewhere else in the community, i have thin rings on one end and thick rings on the other. will this be an issue come tillering time? is there anything i need to be on the lookout for before, during, and after the tillering? this may be the piece of wood i have been waiting for, for a long time and i do not want to mess it up.
