You'll should already have read about grease pencil lines on the hinges, and pins to help you keep the hinges aligned while installing them... (the lines prevent the glue from staying there, and this prevents the CA from making that portion brittle, reducing hinge life. The pins keep you from over-inserting the hinge, and aid in keeping the grease line on the hinge line.)

Forget the drilled holes, they don't really do anything.

Put a drop or two of thin CA in the hole in the aileron the torque rod will slide into... take a drill bit and clean the hole. (*SAME diameter as the torque rod wire!) The CA hardens the wood, preventing the rod from wallowing the hole out as fast. The wood typically swells a bit with the CA, which is why you need to clean the hole out.

Carefully slide the hinges into the trailing edge of the wing.

Slide the aileron onto the hinges and the TORQUE RODS. Gently wiggle the aileron side to side (root to tip) and the hinges will go in easier.

With the aileron on as far as it will go (should be essentially no gap) move the aileron down appx 30 to 40 deg (the beveled front of the aileron will be flat against the wing's back edge.)

Drip 4 to 6 drops of THIN CA on each hinge from the top. You can apply one drop per hinge, and then go back and do each again.... as long as you are reasonably quick. (if you drip 6 drops on one hinge quickly... some will run off, which is not good...)

Flex the aileron up and down a few times (about 10 or 12 cycles, full deflection each way)

Flip the wing, deflect the aileron down again (the open gap is up... I'm not saying toward top or bottom of wing, just whichever side is down.) Apply 4 to 6 drops CA per hinge again.... flex the hinges again.

Repeat for the other aileron.

That should have the ailerons installed properly.

If you have any questions at this point... take the wing with the hinges NOT INSTALLED to the field, alng with the hinges, ailerons, CA... and ask one of the experienced guys to help. Should be no problem. (no one wants to see yor aileron fall off while you are flying.)
