How do they make semi-round pickets?
I mean fence pickets that are convex on one side and flat on the other.
They used to be made by cutting the center out of a tree in the form of flat boards and then the small pieces on the sides were already semi-round.
But my friend thinks they are milled. Wouldn't that be too expensive, to make the cutting wheels?
I have had a few pickets that seemed like the round side was really 3 narrow flat sides in row. But afaict they were in the same batch as a lot of other pickets that were clearly round.
