Do any of you guys know where or even if you can buy osage cut into boards?
Yes you can get Osage in boards. It can be kinda pricey. I'm not sure where you are in Ohio or what size boards you're looking for.
I know woodcraft usually has some and I believe Keim also has some.
If you live near an Amish community you may find a Amish saw mill with osage.
You could PM Kennym I got some nice osage lams from him a while back I think he had some boards !
Try Byler's Kiln Drying on Nauvoo Rd. near Middlefield. 440-477-6458
I have some that are about 2" thick and various widths. I'd be willing to let some go, but shipping from no may be pricey
