Brief Description: Riveting the Rear Spar Receptacle Support
An easier job to follow the battle of the ribs.
Here we are sandwiching the "C" shaped parts between the bulkhead and the retaining plate. Once riveted we have a hemispherical slot into which the rear wing spar will eventually be slotted.
Pictures 1 and 2 show both sides of the riveting on one of the two end of the bulkhead. I riveted from the bulkhead side, as this seemed easier. All pop rivets for a change, and all of them accessible with the air gun. Easy! Just make sure you don't rivet the bits on upside down.
