Good day today, I was able to rivet the skeleton together and clecoe it to skin to check everything. Tomorrow I will remove skeleton from skin, place RTV on the trailing edge reinforcement rib rivets and reassemble for final rivet. RTV is required to dampen vibration which might cause stress cracks later on.
You may note a bit of green on rivets of elevator horn in lower picture. Although Van does not mention this, it is good practice to apply wet primer to rivet before inserting into hole and squeezing when riveting steel to aluminium parts.
