bugs love osage (bodark) sap wood. also i have seen kiln dried osage lumber, its not pretty. full of huge checks warps. I have two staves i am speed drying right now. I have doing it as slowly as possible for 2 months. first i qtr the log, removed the bark and sapwood and sealed the backs with urethane and the ends with titebond III. then i let the staaves stabilize for a week. then they went into my hot box at 110 degrees. I take them out and look for checks every nite. I've started working them down to bow deminsions last week. they will be floor tillered today. and then in the box for 2 more weeks before final tiller. the point being, that this is as fast as i would go. I say give your staves time to dry it will be worth it in the end.
