@Pabs Not only is there no added camber* on mine, I didn't even take out the saw marks ( Japanese saw ) nor sand it, nor varnish it.
It was remarkably smooth wood in very good condition for wood that was blocking a river, absolutely straight, PSE lovely, I reckon if I added it all up, I've probably got about 1.5 cubic metres of it, mostly in 50mm x 150 / 200mm widths.Nice grain with a lot of figuring too, and very dense, the things people throw away ( especially into a river ) amaze me.
Some of it is probably going to be carved walking stick handles, ( animals, mythical or existing ) maybe some "portrait" handles and some Celtic themed designs. One big piece ( which my feet are currently resting on ) is going to be the top of our fire surround, it has grain that radiates out from the centre like a wavy Japanese flag, or a Bridget Riley inspired Robert Crumb background sky.
When I've finished sorting the chaos which is my workshop, I'll carve one** and put up a photo.

**SWMBO would like me to cut two window openings,put in the windows and build kitchen cupboards, in the north facing kitchen wall and insulate that side of the house first.
