Low friction ring fiddle blocks (for runners)

[Matt Johnson]

I've been playing around with making our runners (running backstays) out of a cascade system of low friction rings and dyneema. I've hit a roadblock with the height needed for the system to work, being able to pull them forward when not in use and not having even the light weight Antal ring swinging around when stowed..... there is a reason everyone uses winches or fiddle blocks with runners, but I had to try the idea. This experiment has now been scrapped and I've moved on to the next option....

I've decided to instead make fiddle blocks out of two Antal 10mm and 20mm low friction rings (one with a terminated line stacked like a becket) and have a typical block and tackle arrangement with a cam cleat in the cockpit. I'm stuck on how others are lashing these rings together. I've seen plenty of photos online, but nothing with an explanation or recommendation on how to lash two blocks into a fiddle block. Any ideas?

I was originally going to make a continuous loop just a bit larger than than the two ring's outside diameter.... then maybe stitch or lashes it together in the middle between the two rings capturing them within. Based on a few photos, it seems that others have just wrapped it around a few times then just tied it off.

Any suggestions on how to do this and keep it secure?

Here is a example I found online of the upper part of this tackle.





Thanks,
