I started countersinking the spars for the rivets that will hold on the skins. First up is to rivet the ribs to the spars using the forward holes in the tank attach section. You can see one rivet set just above the cleco to the left and another countersink to the right that is ready to receive a rivet. The plans don’t mention anything about these holes, but the tank will cover up this area, so it only makes sense to rivet these.
Here you can see all of the holes that must be countersunk along one side of one of the spars. There are over 600 holes to countersink on both sides of both spars. I’ll shoot some primer on these before riveting everything together.
