Tension strength doesn't matter. Stiffness does. The application here is in building fire hoops... a performance art thats basically hoola hooping with 5 kevlar "wicks" attached that are set on fire. I'm trying to devise a way to make them removeable, so I placed an order for a ton of these that will attach the wick to the hoop... and I want to use a 5" flexible wire rope to attach the kevlar wick to the hoop. Those standoffs say the diameter of the swage fitting is 3/16", but I dont know if thats the inner or outer diameter, so I assume either 3/16" or 1/8" wire will suit me. Since these are made for swaging, you'd think the inner diameter would be 3/16 (so you could simply just buy 3/16 wire) but I dont know if I should make that assumption. Mainly my question is what is the best wrap style to get the most stiffness. I want them to basically be straight and not droop, but have some flex in the event the hoop is dropped or hits the ground. I'm thinking either this or this or this or this would get the job done. Prefer to go stainless, unless theres a good reason to go galvanized. Would the 18-8 with the thicker strands have more stiffness than the 302/304 with narrow strands? I found a source on the net saying 18-8 and 302/304 are discriptors for the type of stainless steel and mean the same thing, in which case I dont know what the difference is in these products (or just dont understand it, other than what I see in the pictures.) I'm probably going to just order 10 feet of a few different onces and see which is the best for this application, but thought I'd run it past the engineering geniuses on TB first!
