[QUOTE="bigbang, post: 3226353, member: 576408"] Yes. The reason 180 bends arent too hot is because imagine a car driving down the road and trying to do a high speed 180. It will crash into the wall. Easier to just take a couple turns. Along with the analogy, putting triangular Kerfs, I think they are called in the corners also helps. Kind of like banking a road on a turn. The measurements I told you call for the slightest bit more wood because the port isn't sharing two sides of the same board, so the volume of the box will drop by an insignificant amount.
