Prepared J-channel, clecoed skin, final drilled #40 and #19 for the screws. Dimpled all the skins and J-channel. Countersunk the spar using the jigs prepared.
One hole has been ruined and will require an OOPS rivet.
Decided not to implement the step 8 (modification of the lap joint) neither on the left nor on the right wing. risk to ruin is to high compared to benefit. Unclear to me if the lap joint has been modified on the top wing skins.
