Got some oak at Lowes the other day & made hardwood jaws for my vise. While I was at it, I went ahead and built the flange straightening tool I saw in some other builders logs. Used it today to true up the edges on the H/S ribs, although they didn't need much. Also fluted them so they lay flat. In addition to all the ribs, I worked on the fwd spar assy and got most of the way through it. Was worried about trimming away too much in a couple of areas and running into an edge distance problem like I've seen on a couple of other build logs, so I left plenty of extra where I could, and will trim it up for final assembly after everything is match drilled together. Will cleo the skeleton together next time, then final trim the center section.
