1/4" pins to 5/16" pins and reamed out the holes accordingly -
'oversizing'
you call it.
David,
You've got a crossed message here...
The pip pins, as you correctly describe, are used to hold the
stabililators to the torque tube.
The oversizing has not been done to these but to the pins within the
body of the aircraft holding the central parts of the torque tube
together. As you will see, these pins are retained with split pins and
are therefore referred to as permanent pins.
