Finished the assembly of the heater inlet flaps to their respective hinges. Used countersunk flush pop-rivets with the countersunk head against the surface that will contact the cooling duct. I had purchased a nice 2 1/8" hole saw to cut the holes in the duct. Unfortunately, the arbor I purchased to go with the saw (size directed by the packaging) proved to be too small. Was unable to continue.
There will be no update next weekend, 30 Sep & 1 Oct as other obligations interfere with Europa work. Next update will be 7/8 Oct.
