I finished stitches the obstructed ribs. Karin decided to sit out in the garage and do her bible study while I worked on the ribs. I was really nice.After she was done, we walked over to the yogurt shop and had a yogurt together.

After stitching all the ribs, I covered them with pinking tape. I first applied a layer of glue down that extended about 3/4" off each end. I then applied the pinking tape and, using MEK, we the material down and smoothing out with my gloved hands. I then continued down the length of the rib and cut the tape about 1/4" from the rear edge. Was able to get both sides of the wing taped.

Today, I decided that I would mark the rib stitches and punch the holes for the thread. I made a mistake marking the rib stitches right off the bat. But, it was easily corrected. The correct way, and the way I did it correctly, is to mark off 1/2 S from the leading edge of the rib for your first mark. S = 2 1/2 inches in the prop wash and 3 1/2 inches outside the prop wash. I marked my changes on the material with a plus sign. 

Marked rib stitches

After I marked the correct rib stitch locations by the ruler, I went back and moved the stitch locations where an obstruction would be. I then went back and marked a "O" on all the ribs the had the compression ribs in place. 

I then went back and punched out the holes for the thread with the tip of my pencil. On punch was a little larger then I wanted but it worked out fine in the end.

I was surprised how fast that went and decided to start stitching my unobstructed stitches and see how far I could go. I was surprised that I was able to get all my unobstructed ribs done. I remembered that the trailing edge on all but one of the ribs was unobstructed so I stitched those as well.

I was actually able to get a couple ribs on the top with the curved needle for the obstructed ribs as well. My back was hurthing me, so I had to stop.

Akplied the rib reinforcing tape to the ribs this evening. I measured out a strip of tape along the rib and cut to length. I then counted the remaining ribs that need reinforcing on the side exposed and cut that number of tape strips. Starting at the leading edge, I removed the self adhesive backing and lined up the edge of the tape with the back side of the leading edge former. I them carfuly applied the tape down the length of the rib. Turned the wing over and repeated on the other side.

I was able to shrink the fabric on the top of the wing. Started from the rear and ironed one panel at a time. I then moved to the leading edge and removed any winkles I saw being careful not to crease the fabric.
