I have 60' of tube nylon that I cut into (3) 20' sections. The two sections closest to the deployment charges I slid a 36" cord protector onto. In the past I had trouble with the loop around the eye bolt burning...
Slid the shock cord in with the link...
...and tucked the protector in. Now the whole cord is better protected.
One thing I saw a friend do was to zig-zag the shock cord back and forth to keep the cord organized and prevent tangeling...
He then placed some tape around it to keep it inplace. With a few strategicly placed cuts...the force of the ejection tore the tape but only after it was all thrown clear of the air frame. Test fires in the back yard proved it worked smoothly.
Here was the simple jig I put together.
I also put together a 98-76 reducer.
This is where I had to stop work. I got the airframe coated with epoxy and W-410. I've sanded smooth and have a couple of spots to fill again. My garage isn't heated so I will need to wait till we get out of the 20's to continue...
