I had to completely redo the side stringers. The ones that were on the fusalage were not right, crooked and sloppy work.I used the classic plans to make new formers to hold the new and old stringers. I was able to use most of the old wood. Had to snd it down and stain it to get the look that we wanted. I also made some additional pieces because the old ones were not enough. I then pieced them to the fusalage after using string to determine the proper spaceing.
