Most of the folks I talked with seem to think it doesn't matter whether its white or red, black. I know that anything other than white will rot in short order. Anyone have any thoughts on other woods that might serve? I was also thinking about laminating some thinner stock with some splines and epoxy. Thoughts?
White oak is fine if you're going to paint
it, I might avoid it if you are going to give it a natural finish like oil
. White oak will develop black stains that cannot be removed when it gets wet, which it will since its a Sampson post.
Teak, Purple Heart, and any of the others are fine if you like cutting down the rainforest and have wads of cash laying around.
Alternately, you could use local (to North America) and sustainably harvested Back Locust as has been a part of the American boatbuilding tradition for hundreds of years. It's denser than teak and has great rot resistance, Abe Lincoln used it for fence posts. You can leave it unfinished and it will turn silver like teak but not rot.
Or you could just keep cutting down the rainforest.
