Short Description: Aft root rib installation
|
I fit the aft root rib and started to do the updrilling. I only had aft rib #1 attached with clecos so that I could remove the rib to make access to install the root rib much easier. I ran into some issues doing the updrilling. Even though I had more room, I still needed to use the tight fit drill attachment to get to some of the holes for updrilling. I ended up breaking both of my threaded #40 drill bits, so I had to stop for the day. I ordered some replacement #40 and #30 bits and will continue when those arrive.
Aft root rib fitted and clamped in place.

Removing rib#1 gives needed room to drill and cleco root rib to bracket.

Busted threaded drill bits. Arghhhh!
