These are the deck rail posts that I cut using my MulitCam CNC router there are 14 of these posts and the all came out exactly the same thanks to the precision of the CNC.
The flat part at the bottom gets through bolted to the deck frame and the notch at the top will accept a piece of cedar that will tie them all together , then a Cap rail of 5/4 by 6 cedar for the top.
The holes that are drilled through the posts get (vine affect) steel rods slid through which completes the rail system.
This should leave us with an open airy feeling deck. We'll see!!
