Is this needed? Can't I just put an inspection ring on the fabric at that position when I cover the wing? Also it specifies a 4 1/2" hole while inspection rings have a 3 1/2" ID which allow the standard inspection plates to snap into them.Any guidance would be appreciated. Rick HRick,I glued the 1/4" plywood to the spar in that area, and made a recessed area for a round clear Lexan cover, that has 8 recessed screws to retain the cover,that way I was able to use the Lexan (not plexi-glass) for the cable fairlead as it passes through the clear cover. I also used this method in the center section, but there is no cables passing through it in the center section. Theway the plans are drawn (Drawing No. 4), there is no accommodation to keep thecable from stepping out of the pulley on the leg pointing toward the aileron control horn. There Always Must be something to keep the cable from jumping, or stepping, out of the pulley, on each leg. It has to be close to, but not touching, the cable. On the leg pointing toward the center section, the bracket itself keeps the cable in the pulley. This has worked well for me, andif I were to do it again, I would do it the same way. You can clearly see how it works on this page of my web site: http://nx770cg.com/Wing.htmlChuck G.NX770CG________________________________________________________________________________
