Finishing up fabric work on the left wing

We applied more glue to the leading and trailing edges, and then applied a 6" finishing tape on the leading edge, and two 2" tapes on the trailing edge.  These tapes were wrapped around the edges of the wing.  The tapes were ironed in places to eliminate any bubbles and fix them in place. 

We used a soldering iron to burn holes through the fabric at various nut-plate locations, including those for the wing tips, pitot tube, and pulley covers.  We also used razors and X-ACTO knives to carefully cut out the hole for the pitot tube, and slots for the aileron and flap cables. 

Once completed, we noticed that there were a few additional bubbles that had formed on  top of the plastic inspection rings.  Not sure why this happened as there were no bubbles in the fabric after we first installed the rings.  Perhaps we didn't apply enough glue to the top of the rings, although it's still not clear how those bubbles formed.  In any case, we ironed out these bubbles, and will keep an eye on them to make sure they don't come back.   Hours: 7
