    Alternative shock cord mounting technique

    Probably not new. My D-Region Tomahawk needed its 3rd new cord, and I've had enough with teabags. Here's the interior after cleaning out the old tea bags:

    I decided to use a 2" section of 1/4" launch lug (Loc part #LL-25), and just thread the new cord through it.

    That's the rough idea. I am not overly concerned with the chute catching on the lug - it's a big enough body tube, but I'll certainly pay attention to that when folding and packing.

    Here's the lug, mounted with some Loctite 5min epoxy. Top of the lug is 2 1/2" down, enough clearance for the 2" nose shoulder.

    A thought: Drill through the bottom of the MMT Centering Rings, between MMT and BT, then run Kevlar Cord through the hole. Pull through to NC end of BT, then tie a loop into it. To the loop, tie a length of Bungee Cord between it and the NC. With that in place, pull the Kevlar Cord back to a length just short of the BT (to prevent a zipper), the cut the cord, tie a knot in the end and sufficiently glue it to the outside of the rear centering ring.

    All the weird kids are doing it!

    If at first you don't succeed... You're about average.

    Alternative shock cord mounting technique

    Then I threaded the cord through and tied an overhand knot. Pretty sure the lug won't separate - appears bonded well, plus I used an extra long cord (around 6 feet of 3/8" sewing elastic).

    The finished product:

    This particular rocket makes that impractical, plastic fin can and a challenge to get to the innards. But interesting idea for another bird for sure.
