The Pitts Aircraft Upper Wing Assembled.

I started making the set-up blocks for the front and rear spar that would be mounted onto the table. With the blocks made and mounted, I started installing the ribs. A little sanding here and there, and they fit. After all the ribs were fitted and marked, I went to the next step. But what exactly is the next step?  The prints did not come with step-by-step instructions. By now I was wondering, “What have I gotten my self into”? So I flipped through the prints until I found the next thing I could build. This turned out to be the metal pieces.
