We spent about four hours fabricating the rear wing channels for the left and right wing.

The manual gives a kernel of a good instruction, but there was an easier way. If you mark the edge distance and then mark your rivet holes on the outside of the channel, you can support the piece ( placed in the jig ) during drilling with a small piece of wood underneath it. When you back drill, use the same piece of wood with a clamp to keep parts from shifting.

The first jig was set to a length of 600mm for 7V6-2SP. The manual states that for 7V6-1 the jig should be set to 380mm, BUT the length of 7V6-1 is 380mm. The plans state that the flange-to-flange distance of the completed part is 400mm, so I think the manual is in error.

The Zenith list seems to concur, but I'm going to call Mexico, MO in the morning.

Also, Robert from my EAA chapter dropped by curious to see what the Zenith build process id like compared to the RV-7 he is working on.
