And some more work on the F-706 Bulkhead - 4 hours

Managed a decent day in the garage today. One of the tasks needed to be done was to open up the 7/16" diameter holes in the F-730 plate, the F-728 and F-729 webs. A little bit tricky to do, but best way I though was to mark it and then slowly chip away at them. Fist step I cleco'd the F-730 plate and marked it.

Next I cleco'd the F-728 and F-729 ribs and marked those.
 
 I pulled out the dremmel tool and with a very small diameter sanding drum I started in on removing material.

I then used very small round chainsaw files and sneaked up to the line. It took a few tries but I managed to get things close.

Once I was happy with the pieces, I cleco'd the assembly back together and used the dremmel one last time to even the holes out. After that, everything was debur'd and edges were files down.
