Next an M2 brass nut is threaded onto a closed loop adapter that is then in turn threaded onto the snap link

Next a small pre cut length of aluminium tube has the trace wire threaded through it. The wire is then threaded through the eyelet at the end of the adaptor.

The wire is then doubled back through the aluminium tube and pulled to form as small a loop as possible. Once completed the tube is crimped with a pair of pillars to prevent the wire from pulling back through

Once this assembly has been completed it is placed on the rigging anchors that have been soldered to the wing strut plates.

With this end made up, the other end of the wire is made up in the same manner as just described but without the swivel. this time the snap link and adapter assembly  directly  placed in situ on the model before the wire is run to the required anchor point on the model. This allows the wire to be pulled to the correct length  before crimping and cutting.

Once you have completed this procedure the wires should be reasonably taught, but can be tensioned further by rotating the snap link until correct tension is achieved.

All that is now required is to tighten the brass lock nuts to ensure that everything remains in place.  

This picture  and next, showing flying wires at fuselage. Note that as mentioned in the last picture no swivels have been used at these ends
