Wings, Flaps (Part 14)

During the last session, many solid rivets were installed in the Top Skin.  During today’s session, more solid rivets and blind rivets will be installed in the Nose Skin.  Here is the leading edge Nose Skin above the Outboard Hinge Bracket.  This rivet location uses eight MK-319-BS blind rivets as shown in the black box.  The leading edge Nose Skin above the Inboard Hinge Bracket was also installed.

The inboard end of the Flap uses both solid (AN426AD3-3.5) and blind (MK-319-BS) rivets.  Just as above, the holes receiving the blind rivets had to be final-drilled to #33 prior to installing the rivets.  Here is the top side of the inboard end of the Flaps and you can see the four blind rivets on the left and the solid rivets on the right.

This is the bottom side of the inboard end of the Flap (opposite side from above).  This side receives the same rivets as the top, but only three of each rivets are used.

This is the inboard side of the Flap.  This shows the Nose Rib with the solid rivets installed (next to the blind rivets above) on the Nose Skin to Rib Flanges. 

The outboard end of the Flap only receives solid rivets (blind rivets were only installed on the inboard side).   Here are the seven rivets installed on the Nose Skin to Nose Rib.

I have to stop here for the day.  Prior to setting the MK-319-BS rivets, the holes have to be final-drilled to a #33.  I have #33 drill bits, but in standard length bits.  So, I will need at least a 6” bit to clear the Hinge Brackets.  Below are the two Hinge Bracket locations
