well how is one supposed to use a drill press to ream the holes on 25-06 after the cover ribs (F-01438) and the side angles (F-01403D) in place on the F-01403 bulkhead.
The same thing applies to the F-01404 bulkhead.
Maybe I missed something or they notes are supposed to be reamed with a hand drill.
Any advice would be appreciated. I would prefer to not screw up the bulkheads since they are expensive.
thanks

The word "always" will be removed from that statement in a future revision. It does make it a bit confusing.... The intent was to emphasis using a drill press while reaming
all of the holes in the next step, not the entire airplane.
On 25-06, the reaming is intended to be done carefully with a hand drill, which is the reason for the caution to "Avoid applying any side load".
The intent is for the reamer to be slipped into the holes in the bars as described in the manual text (and as described by others) so that the reaming process produces a hole in the rib, that is exactly aligned with the hole in the bar.
