Work on the map box began by taking one of the map box halves (both halves are identical) and attaching the right instrument panel cover and door to it with Clecos. Next the hinge is set in place and is match drilled to the holes in the door.
Assembling the map box just enough so the door
hinge can be match drilled.
Match drilling the door hinge to the rivet holes in the bottom of
the map box to #30.
After the map box’s door hinge is match drilled to the bottom panel, the predrilled holes in the map box’s door are used to match drill the door hinge to #40. The map box door is then removed and the remaining map box half is mated and Clecoed in position. Next all the #40 holes on the panel cover are match drilled into the map box followed by match drilling all the remaining rivet holes that make up the box to #30.
Match drilling the #40 holes in the panel cover
into the map box.
Match drilling the #30 holes in the map box.
After all the drilling was out of the way the map box parts were disassembled for deburring. Also the #40 holes on the map box cover require some extra attention by way of countersinking for flush rivets …. but did not get to that today.
