" The same 3.3mm drill used for the hinges worked fine
for the rivets. Actually it was difficult to _not_
make a hole below the "V" when you drill through the
hinges. Due to the proximity of the two surfaces of
the "V", once the drill pops out of the flange, it
hits the next surface almost immediately and makes a
hole."
Indeed - it's a good idea to put a thin Al plate under the hinge when
drilling to protect the vee - although as previously discussed, you'll
probably end up having to put holes in it.
As an item of interest, the glider wing ailerons are so thin that the vee is
even tighter and there is no option but to put the holes in it in order to
pull the rivets.
