Thanks to Brian (JDBrian), I have thought a bit more about this. I wanted to get the end posts closer than 18-24" to the ends. One end had the factory drain for the gutter.
These were going to keep the posts back about 8" from the end. Daniel and Brian got me to thinking about enclosing this. That meant the posts need to be much closer to the end. So I drug out one side and an end to figure how to drain the water. I was able to figure out how the two pieces went together & what I could do. The X in the below pic is what I can cut out for drainage.
Then after contemplating this for a while, I got out a downspout bend to help get a clue of what to do. I have several pieces of some heavy sheet metal, thanks to my son, so I started bending and cutting.
Having trouble getting pics to load for some reason. Just won't upload. I'll submit this and try a reply.
