I think I'm going mad.
Ive drilled all the WD-1021-PC Landing gear mounts to the bulkhead with a #12 drill as instructed.
I need to machine countersink the 2 holes shown for a #10 screw.
My #10 countersink pilot clearly won't go in a #12 hole.
What am I missing?
How do I countersink these holes. Is such thing as a #12 pilot countersink?
