Attaching steel rings

[Goinav8n]

I just bought a huge piece of rubber to launch my 3 meter. Its a 50 foot piece for landing practice.

How should I attach the steel rings so they wont come off? I would hate I mean really hate to have this come off. Do any of you have some pics of how it is attached?

I was thinking of streching it and wrapping the end with spectra or something and then using CA to keep it from unwrapping.

Any other ideas

The first photo has the knot I have seen used most often. Not sure of the name. I think of it as tying a neck tie knot. I don't add any glue, string or anything else. Just make sure there is a bit of a tail, as you see in the photo.

The second photo is of the second ring where I used two half hitches. That has held just fine also with no need for glue, string or anything else.

As far as I can tell the first knot you have there is known as a Lark's Head knot. Just so others can look it up if they can't tell what's goin on =)

To tie the first knot, as you face the ring:

front to back thorough the ring
turn right and come forward then to the left across the tubing - leave it slack
From the left side - go through the ring from rear to front
slip the tubing under the crossing piece leaving about 2 inch tail.
Snug it all up - go fly!

here's another picture of that knot, pardon my bad drawing skills.

I have a 25 foot piece of 7/16 tubing and 150 feet of mason line on my upstart. I launch my 2M planes at 12-14 lbs of pull. Works very well. Have also launched 3M off this up-start.
