Over the past couple weeks I cut and trimmed the 2 pieces of Balsa wood that the shaft for the trim tab goes through. The plans call for 3 pieces of 3/4 inch balsa wood glued together. I couldn't find 3 pieces but I found two. So I very inaccurately cut the same channel down both pieces and glued them together. It isn't pretty but it is functional. I will clean it up with some sanding and add the bolts under it before varnishing the entire stabilator.
