I need to repair a split rail fence. It is a fairly long fence and is in pretty good, solid shape overall except for one post that has rotted at the base were it contacts the concrete footing. The part of the post above ground (3') is fine from what I can tell. Initially, I thought I would just replace the one post and footing, but the split rail fence posts that I've found locally aren't a very good match to the existing post. Namely, the spacing between the upper and lower rail cutouts do not match (18" for existing fence, and 14" for a new one). Also, the existing fence is a nice weathered grey, and a new post would take a few seasons to start to weather so as to blend in with the rest. Thus, it would look sorta funky for a while. So, I started thinking about ways I might be able to salvage this post. I had an idea that I could maybe remove the post and concrete footing and hammer a couple of long metal rods/pipe (maybe thick rebar?) into the bottom of the post (I'd have to pre-drill first, of course). Then, fill the post hole with concrete and insert the old post back in and brace while the concrete cures. Sounds a little crazy, I know, but do you think this would work? Might be a little more shaky than the other posts, but as long as it stays plumb that should be fine.

My house had an old fence on it that was starting to fall apart so my wife and I tore it down a couple weeks ago. We are replacing it with prebuilt wood panels that I'm going to cut down to 4' tall. We are keeping two runs of the fence (these posts are still in the ground to use as a reference for a line and spacing), moving back one and tying it into the edge of our garage (this is just one side of the yard for the time being). I have not built a fence before or worked with prebuilt panels so this is all pretty new to me. I see that the panels are made to attach to the outside of the posts. How do you do the corners to make them look good? Also we will have one inside corner where it ties into the garage...what will be the best way to make this look decent? I'm going to attach a pressure treated 2x4 to the edge of the garage with tapcons (this was how the old fence was put in) but I'm not sure how to bring the panels together at the inside corner to make it not look weird, and unsure of how this will affect post placement. Any other pointers are much appreciated.
