Thanks for information on drawboring. I will likely need it when I want to peg the joints. I am still in the information gathering stage of my repairs and trying to select sound timber of a correct size to make the repairs. I will likely need some recommendations when I am farther along. I think I have a good rear wall design based off the front wall. The rear wall needs to attach to (4) 8" timbers with partly rotten ends. I will post drawings and pictures for a sanity check before even picking up a saw. I have found that a few extra sets of experienced eyes is the next best thing to experience.
