Some guys have boxes with heaters and fans inside to dry their wood. I work the stave till its string-ready, over time, and put the stave in front of the blowing wood stove and dry it each day I can. I also have a long tube that I put wood in and have a sacrificial hair dryer set on low blowing through it. I think the key to drying wood is the moving air.
I'm thinking about a bow display case that is, in effect, a humidor of sorts that keeps all my finished bows, and maybe future staves, drying all the time.......?
