Marc,
Great recovery work; that would set me back far worse than you. I accidentally snipped a bit too much off of the wing tip (to fit the late style ailerons) and had to fuse a piece of styrene rod onto the end which I was able to sand down to fill the gap, but my repair skills are pretty ham-fisted compared to what you were able to to.
Gene,
I wouldn't normally answer for Marc, but since I am 75% of the way through the same model, I'll see if I can help. The Snipe used flat aerodynamic wiring for the cockpit framing for which I have used Prym knit in elastic. From the pictures it looks like the same material that Marc is using. Similar to EZ-Line, the Prym stuff stretches, so it is a bit easier than fishing line to keep taught. The easiest way, assuming that you can get the CA glue to hole, is to glue one end directly to the frame, cut the length a bit shorter than the span so that it stretches, and then glue the other end. This is what I did for my internal framing since it is pretty hidden, and details are hard to see. You could also drill holes in the framing, and pull the rigging through, tighten and glue.
For the exterior rigging, I preferred to glue tiny eyelets at the attachment points, and loop the rigging material through those. Pass the line through a piece of brass tubing, then the eyelet, then back through the tubing. You can tension the line by pulling the tag end taught, and put a drop of glue on the tube end to set it.
With non-strecthy material (fishing line, for example), its either eyelets & tubes, or drill and pull as far as I know.
