JI9,
I am in "varying humidity" southern Arizona. Oak boards have been mixed success, meaning more break, lift a splinter really, at various lengths than stay intact. I think the kiln process is done out in Texas, PA, or MO, somewhere else. When the board hits June aridity, the change "does them in." Gambel oak may be the best route, meaning a stave. LChucks oak bows look like a template to follow.
welcome, btw.
