Oh dear, which means I've just wrecked a whole lot of parts. I'll have a
looksee with a magnifying glass. I did try to cut them out to 7.9 mm, but I
was afraid it might be too deep a cut and that the triangular hole cut by
the drill might leave it's remains around the edges.

Don't make any assumptions based on my comments. I am unfamiliar with
the plane you are building, I do not know the metal variety you are
working with and have not seen the parts. Finally, I do not have
experience building enough airplanes to rely on experience when
answering you. Metalworking I do know about, so I could make a pretty
good guess as to what your problem was and the probable ramifications. I
suggest you talk to the designer of your airplane or another builder of
it.
