Note taken on using rib-lacing cord instead of safety wire to secure the bungee loops. I must say, it seems that the rib-lacing cord might have a lesser possibility of damaging the bungee than the safety wire. Another member of our EAA chapter just finished rib lacing his Kitfox wings, so maybe he has enough left over cord to do the 4 loops.
Thanks to everyone for making suggestions and offering input on the topic!

Here's my home made bungee story.
I used round rib lacing cord to wrap a couple bungee loops. One I wrapped the bungee while it was slack. I then put the loop over a pipe in my bench vise, put one foot up on the edge of the bench and pulled as hard as I could. The bungee slipped through the wrap.
I wrapped another loop with the Bungee loop stretched. This one passed my pull test. You need about 5 or 6 inches extra length on each end of the bungee so you can clamp it in a vise. Then hook a come a long in the loop and stretch it tight and hold it there while you wrap the loop.

Yes you need to stretch bungee to wrap cord, otherwise it will pull out. I just clamped in vice then tied a rope thru the loop to something solid with a couple of sheep shank knots (truckie hitches)stretch it out, then wrap. Tom
I did mine by carefully clamping the cord in a vice and made a mark on the cord that was two inches from the end of the loop. I then used a scissor jack against the vice and attached to the loop to stretch the loop until the mark was four inches from the end of the loop. Then I very tightly wrapped about 8 turns of .040 safety wire around the bungees at the mark, being careful to bury the ends so they wouldn't get caught on anything or come unwrapped. Then I backed off the jack and took the bungee out of the vice, trimmed the end and went on to the next one.
Each loop took about two minutes, and came out GREAT.
