I stored a hickory log in my garage rafters back in the day quartered, and wet before I knew better. They all twisted, and were useless in the end. After that with hickory I got the staves to floor tiller wet, and clamped them to a 4 inch reflex form, and let them dry in my basement. I have enough forms to take care of the staves ,and they dry faster. If I want to fire harden one, I take it off the form string it backwards, and toast the limbs over an open fire with leather welding gloves.I get good results with hickory that way. More than one way to skin a cat.
