Tung oil dries in essentially 48 hrs. Then it prefers another 3 days at least to cure. Sometimes, depending on humidity, even longer.

If I'm working on a restore for someone, and I've got to do exotic wood with a tung finish, I'll make the scales before I start buffing the blade. That way they have lots of time to set up. Personally, I'd leave it for a couple days. Then after the cure, go back and buff it. If you don't have a buffer, get a cotton towel and rub as fast as you can!

Did you apply tung straight, or did you burnish? I can't see the grain from the previous photos....is it a loose grain or a tight grain?

Edit: Rosewood has lots of oils in it....for future reference, you can sand it up to 2k and then buff it out with white rouge to get a really nice and smooth finish.
