Nick,
When I was a youngster, my dad used to argue with me saying "you can do it
any way you want to, but if I were doing it", and then he would proceed to
tell me his way to do something.
Well, I won't say it quite that way, but here's an idea that is especially
useful for the wings and ailerons.
Drill the holes smaller than for the rivets and use # 6 sheet metal screws
(4 per hinge) to hold things together. After checking the folding
operation and making any minor adjustments to hole location, remove the screws
and
drill all the holes out to the rivet size. Be sure to mark each hinge
assembly so it can be properly repositioned after covering, because the hole
locations will probably not all be exactly alike.
This was not my idea, read it somewhere, maybe even in my Kolb FireStar
builders manual.

Hello Kolb builders,
I have all my surfaces ready to cover. I have laid out my wings flaps and
ailerons. The only thing I have not done is drill the holes to test mount
the hinges. Is there any reason I could not wait and drill the hinge rivet
holes once everything is covered? Thanks as always for your thought!

I use Teflon spray on almost everything because once the carrier evaporates
the lubricant left behind is completely dry.

As James and John pointed out, you need to deburr all the rivet holes
before riveting. This does two things; removes a potential starting point
for a crack later on, and if left on, the burr acts as a shim that
deteriorates with time due to vibration and gradually allows movement of
the no longer tight joint to begin wallowing out the rivet holes.
One other thing about drilling around tightened, doped fabric; if your
drill bit slips off the tube and slides to the wrong side of the tube you
get to practice patching on your nice new cover job.
On the up side you'll create combinations of swear words and descriptions
of ancestry probably never heard before.
