Let me state some findings and nonconclusive results yet here,but ill share with what I have found out so far as to quick drying various types of wood.
Whenever I harvest a species ill take one or two staves and reduce them to floor tiller(bending no more than 6",and def no more than 8")..it seems the 8" mark or around there is when dripping wet green wood starts to take set. I then write that date down onto the piece of wood the day i floor tillered it and ill weigh it immedietly and record its starting weight. Then once a week ill weigh the stave recording that number. Then its just a waiting game of when it stops losing moisture.
Here's a list of the woods I've been experimenting with in quick drying.......all these have been harvested by my own two hands
Osage....yew....black locust...hophornbeam....american hornbeam...hickory...eastern red cedar...elm...rosebay rhododendron....serviceberry...
...I might be forgetting one or two....but here's my point.
Out of all these woods ill start with the slowest
Osage...by a milestone it loses its moisture slower than any other...but it can be quick dried CAREFULLY..and needs to be closely monitered and babied
Hickory....its a dog that loves to slobber and salivate with moisture..lol
HHB and american hornbeam....it seems so dense from its compact grain and small ring structure that it like to hold onto moisture as well...but my record from stump to shooting bow is 36 days with an american hornbeam...and yes it was dry because I heat treated it deeply with no checks.
Serviceberry...not too many comments...just average
Elm....it dries pretty quick when reduced
Rhododendron...its the wettest wood when cut...literally dripping wet...but dries farily quickly and the back should be sealed after debarking
The next are all fairly close and might surprise you
BLACK LOCUST...when the bark and sapwood is removed it'll lose moisture at a very rapid rate..it surprised me big time. But if the bark and sapwood is left on it really holds onto its moisture.
Yew...yup I said it ....yew. it can be quick dried n must be carefully monitored,but if debarked and reduced to floor tiller it loses its moisture fast....so fast it'll want to move in every which way on ya....so if ya don't mind heat corrections then go for it.
Eastern red cedar....enough said there...I believe juniper wood fall into this category as well since its a juniper.
Hope this helps some folks and opens up some discussion
