Brief Description: Flap Mechanism 5 Drilling Block Holes in floor
Before drilling the holes in the center bearing block I used a drill and marked where the holes would come out and examined the locations for good position on ribs and edge margins. The forward hole was a problem for my brother. Mine looks okay and I think it is because I got the hole drilled in the bloock a little aft from where it is shown on drawing. So good deal.
I drilled the holes. I'll put platenuts on these later.
