Brief Description: Initial assembly of starboard wing skeleton
It was really cold in the shop today but I decided to forge ahead anyway and much was accomplished. First item of business was to mark and drill the holes in the wing ribs for the electrical conduit. I used the marking template created for the port wing and then drilled all the holes to 3/4" with a Unibit and deburred. The ribs were then clecoed to the main spar. The most outboard rib was drilled for a bracket so it could be attached to the jig.
The edges of the rear spar were debuured using a die grinder and scotchbrite wheel. The inboard top flange was drilled to final size and the holes dimpled out as far as the forked reinforcement plate extends (can't dimple these holes after fork is riveted in place). All the reinforcement plates and the fork were riveted to the rear spar taking care to leave appropriate holes empty. There are about five (5) holes on the extreme outboard end of the spar that have to be countersunk. The aileron mounting bracket will later be attached over these rivets so they have to be flush.
Once the rear spar was assembled it was clecoed to the wing ribs in the jig. In my next shop session, I will level the wing skeleton and do a preliminary check for twist. the last task for the day was to rivet the tie-down bracket assembly together and mount it on the main spar.
Finally, I took a little time to clean up and reorganize the shop. The port wing was moved from the work bench to the stand. The paint table was temporarily broken down and stored out of the way. One of my tool chests was moved to a different wall so the wing stand could be rolled up against an outer wall of the shop. I was able to recover much of my floor space which will make the second wing build much leasier and less stressful.
