The island countertop was delivered on Tuesday. But, it's going to be a little while longer before it can be anchored down.
Apparently, when you take a big piece of wood from somewhere (Tennessee) that has this mystical thing called humidity, to a place (Arizona) that does not believe in humidity, wood does "interesting" things.
Currently, it's got a concave warp across the width, with about 15mm of deflection, due to the top shedding moisture faster than the bottom.

It's gorgeous though.

@shatteredgears ohh that is pretty! Do you have to do anything special or can you just leave it to air dry?
@verityvirtue Technically, I don't need to do anything. It will completely flatten when the moisture equalizes between the top and bottom.
I did oil the top this afternoon though, which slows the moisture loss from the top. That actually helped a bit already. Plus, the top was really dry, it absorbed over 6 ounces of oil.
