Today, I riveted most of the top skin to the root ribs and the R-BULKs. The only thing not riveted was the aft portion of the root ribs, I ran out of countersunk rivets. On order from ACS and they'll be here in two days. Next, I turned my attention to the gussets. I should have riveted the top inside gussets before I added the root ribs. I had to remove the cleco's from the R-BULK sides and pull the root rib out to complete the riveting. I also riveted the lower gussets. Next, I re-leveled everything and then began work on the tail FUS 344 horizontal bulkhead. Tomorrow, I'll locate the corner wraps and get them ready for installation.
