I did the final prep of the top and bottom skins so they are now ready for riveting to the skeleton. This included removing the blus wrap along the rivet lines, deburring holes (for the last time) and dimpling all the skin holes for flush rivets. I fit the left wing top skins to the skeleton. I also added some angles to my wing jig that will allow me to clamp the rear wing spar. I will be able to clamp front and rear wing spars on each end so that the wing is perfectly aligned and square before riveting the skins. You can check the wing for any twist by dropping a plumb bob from the main spar and checking dimension from string line to rear spar. Make adjustments to jig and clamps until it's happy. Now, just need to find a riveting partner...
