Countersunk the flap spar and fitted the top skin - 2.5 hours

Since my microstop countersink was set up still from the main spar countersink. Moving on to the countersink on the flap spar was quick.


I ended up with a countersink diameter similar to that as used on the outboard skin of the wing spar.
I then fitted the top skin.

That's good enough for an evening's work. Time to call it a day.
