Brief Description:	Left Wing - forward and aft ribs on
Worked on finishing the locating of the forward (nose) ribs, and then worked on getting all the aft ribs located. I did things differently from the right wing, and this time it went much better and faster. The difference was 90 degrees. On the right wing I was doing all this on the work table, with the spar web perpendicular to the work table. That meant when I was trying to align the ribs I was fighting gravity; the ribs were always trying to slide down while I was trying to hold them in place for clamping and then drilling. This time I put the spar web horizontal so I was not fighting gravity (photo #1). For the forward (nose) ribs I did all this on the work table. For the aft ribs, which are longer and more unweildy, I put the spar across 2 saw horses so I could rotate the spar 180 degrees as I worked (see photos #1 and #2). In photo #3 you can see the aft ribs being worked over the saw horses, and the forward ribs being worked over the work table, while supported on each end by 2 layers of 2x4's.
