Brief Description: Drilling Canopy Hinge Blocks to the Ribs pt. 2
At some point in the past, I had started on the canopy hinge blocks. Today, I finally drilled them to the ribs. I drilled 1/4" holes in the F-745 ribs using the holes in the C-617 blocks as a guide. I had previously riveted the F-644 ribs to the portion of the F-768 bulkhead I had cut out previously. I clecoed the bulkhead back into position and clamped the C-617/C-618/C-619 assembly between the F-644 and F-745 ribs. I slid bolts into the holes until they contacted the F-644 rib and then clamped the assemblies between the ribs. I clecoed the F-771 Forward Top Skin into position to keep the F-644 ribs in the proper position. I left the skin outboard of the F-745 ribs loose so that I could lift the skin and drill through the holes in the assemblies. I removed a bolt, drilled through the assembly and rib, and then replaced the bolt. Six iterations later, I was done and called it an evening.
