Finished drilling the F-742 seat floors - 4 hours

 Now that I am set up with the aft seat floor hinges its time to drill. I started placing and drilling the mount holes in the hinges to the aft floors using a #40 bit. Then I opened up the holes to #30 

So, its not till I actually drilled the hinges to the seat floor that I noticed the hinge covers the hole that mounts the seat floor to the seat rib. It scared me at first, but I soon realized that this hole falls right in the middle of the hinge. I drilled this hole out and will allow be to still install the #8 screw to attach the floors to the seat ribs (remember I made my seat floors removable).

 

I finished the build session be opening up the #40 holes in the seat back brace to #30.
