This is a milestone in building the wings because when the wings are attached to the wing the jigs can be removed.
Ardrox on the mating surfaces just before left tank goes on:
Tank bolted in place and attached with clecos and rivets:
All aluminium rivets done, next the stainless steel rivets for SB #0014 with some tank sealant to prevent galvanic corrosion:
Now the jigs can be removed and the tank sealant around the stainless steel rivets need some cleaning, but it’s better to wait 1-2 days for this because a bit cured it’s easy to remove the sealant with a toothpick.
