Tonight I started drilling the F-633 control column mounts. Drawing 11 shows a 3/16" hole on one end of the F-633, and then another 3/16" hole match-drilled with the center section once the mounts have been squared and aligned in place.
My problem is that the pre-drilled hole in the center section (F-704B) is quite a bit larger than 3/16" -- I measure something like 0.22" -- probably the right size for those large pre-set rivets in the center section. By the way, all of the other holes in the aft center section (where the seat ribs bolt with AN3 bolts) are also this larger size.
This means those two bolts are going to be working almost exclusively in tension.
Is this normal? After a search here, I did not see anybody else talking about this, so should I just do my best to align the mount at 90 degrees to the center section flange and drill the 'other' 3/16" hole through the larger pre-drilled hole in the center section?
Thanks!
