I cut green, reduce to a floor tiller, align on the form, clamp , let dry , heat treat before taking off the form.Then tiller, heat treat,tiller heat treat all the way to finish to keep set at a minimum with white woods. Yes , your stave will hold it's shape coming off the form, but for me if I don't heat treat the whole way to finish through the tillering process I get excessive set. You may not have to use this process, but it is what works for me. Good luck.
