Re: Pedestal base
It is live oak, about 50% heavier than white or red oak. It is used a lot for the futtocks (curved frames) in large wooden boats.
I cut a piece 1 1/2 x 6 x 12" and it weighs just over 4 pounds, that should be stable
I'll sand it a little and post a photo with a little varnish on it, it has an interesting grain. As far as I know, it is seldom finished. I really like the look when it is.
