I can use a double jaw toggle on the double-ended stud located between the furler link plates, connecting it to the turnbuckle with a threaded eye. (A bolt will do as a replacement, you're right).
Now, regarding the next connection to the rod, which is also part of the bow rollers, I'm a bit confused.
Currently it's like a large toggle that fits on bow roller rod then to both sides of the eye terminal. I'm not sure where to stop replacing
rigging and if that's part of it. I could potentially do away with it and use the unused bollard behind the furler. I'll have extra 1/2" chainplate bar soon which I could bolt or weld onto that. I don't know what it's for otherwise.
As for the terminal fitting through the foil, I will need to check the measurements, as they're not listed. I can potentially fit it on after the cable is run through, though.
I noticed that the bluewave double jaw toggle has a 16mm pin and the threaded eye terminal has a 16.5mm hole, which seems a bit unusual. I'm wondering if the 0.5mm gap is supposed to be there.
Again, thanks for your help and
advice. I'm still figuring out some of these details and any further input would be greatly appreciated.
