There were a couple of areas in the old post that had been damaged over the years, so we repaired those by cutting out the damaged area, cutting a new piece of oak the same size, and installing it with some wood glue. These replacement pieces should not be very noticeable once they are sanded and stained.
We then installed the second post using biscuits, wood glue, and a few finish nails. This post was a bit tricky, as the wall is not perfectly straight, so I had to trace the shape of the wall onto the wood and then cut the wood to match that shape.
Well, the difficult stuff is done and it's starting to look like our mock-up. We need to do some sanding on the posts, install the railing, install some trimwork, and then sand everything to prepare for staining.
