It is essential that this distance is the same both sides, or the ailerons
will not move the same amount each side. The important distance is between
the hinge wire and the bolt. The way I did it (in fact redid it, about 5
times as much as work as doing it right first time) was to make a jig out of
tufnol to position the bolts.
The jig has one hole the size of the bolt shaft, and one the size of the the
hinge wire, drilled parallel and at the correct distance. I removed the hinge
wire and put a straight piece of wire through the jig and the hinge, and the
bolt into the hole and did the glassing work. Same jig of course used on the
other side.The jig needs a bit of shaping to make it all work. it also
ensures that the bolt is parallel to the hinge wire.

<< Gents,
I'm about to attach the aileron hinges but something in the manual is
puzzling me (beyond my usual state of lower level comprehension). It
states that when putting the hinges in place to ensure that "...the
distance from the hinge pin to the AN4-10A bolt is exactly the same for
each aileron."
This made sense the first time I read it, but now as I get close to
actually performing this task, I'm all muddled as to how I should go
about it. What's the best way to measure this distance? Is this
measurement to be taken from both hinges, or just the root's? What is
the best remedy if there is a difference?
Thanks in advance for your replies,
