Actually, I found that the rigging jig works. I've used the method for the Soleil Royal model. Soliel Royal was finished over 20 years ago, and the lines looked just fine, the last time I saw it..
The trick is DON"T use white glue. Mix Testors tube glue with Testors bottled (liquid) glue, about 50/50, maybe a little more liquid then thick.( Test on scrap thread, for consistency). A drop will immediately soak into the thread and disappear.If you want to seize it afterwards, great. But give it time to set up first. A second drop on the seizing will make it, too, permanent.
Warning be very sparing. Excess will, indeed, use capillary action to reach the plastic jig. Do the edges (fore and aft, top and bottom) first. They'll prevent spread from the inner points. You'll also be, most careful, when you start. It's tedious, and you may start getting careless after a while.
Once it sets up finger nail clippers or suture scissors work great for trimming the foot ropes. I looped the thread around the bottom of the jig to provide excess for seizing to the deadeyes.
I liked it, and it was sure easier than mounting the footropes after the stays are in place.
