So this is a close up shot of a completed post with the cap installed. The cap is attached with two deck screws through the top down into the sides of the post.
Some other features of the deck. This is a shot of the steps leading to the top deck. 5/4 by 6 inch pressure treated deck boards were edge joined then cut to fit for the inside piece. Then a straight board was placed for the front.
And this is a shot of the steps leading to the middle level. Again the same method was used. I decided to use a straight board for the outside board because it will be easier to replace when it wears or if the edge breaks.
So here’s a before and after.
