I have purchased the Carlson Extruded Strut material. I need some help with page #55 of my XL drawing package. There is an arrow pointing to the vertical lift strut and to a vertical jury strut. Are they both extruded streamlined material? If so the detail for joining them together is confusing for me. Does anyone have photo of this connection? It looks like three pieces are connected together. The 1/2" round Alum. tube and two extruded tubes all at one connection. The connection at the front and rear spar is not detailed either. Any help would be greatly appreciated.
