Finished drilling the skin stiffeners on the left and then flipped the whole assembly back to right side up on the workbench. Cleco'd the right skin on and marked removed the vinyl along the bottom skin overlap.
Installed the two aft most bulkheads and the bottom rear skin. Took a little while to figure out the orientation of the skin, but then could it is shown clearly in figure 3.
Then drilled the holes for the right side stiffeners. That took a lot of my day with several starts and stops.
Moved on to fabrication of the rudder stop stiffeners and the rudder stop brace. Tricky to get all that installed into the tight back end of the plane but got it all cleco'd and match drilled.
Fabricated and countersunk the bellcrank rib angles and cleco'd in place on the bellcrank ribs. Fabricated the spacer for the aft deck and temporarily held in place on the rear bulkhead with double sided tape. Installed the aft deck and confirmed everything lines up well with the skins and longerons. Ready to start drilling longerons.
What a day. There is definitely a large airplane piece in the garage. Disassembly and priming all this is going to be heartbreaking.
