How do you attach the kevlar in an Estes kit that uses the tri-fold piece of paper shock cord mount? I am always afraid it will just cut right through the shock cord mount. If I can modify the kit to use a Quest style shock cord mount, I use kevlar. If I am building it stock, I replace the rubber shock cord with elastic, just because I can lengthen it a bit and it seems to last longer.I wont every run out either...I quite using elastic years ago in favor of kevlar with lightly taped z-folds in LPR and regular taped z-folds in MPR and HPR.
Not to many Estes kits made that I don't ditch the trifold mount too, there are other ways to mount shock cords. The larger the diameter the tubes the more options I have.How do you attach the kevlar in an Estes kit that uses the tri-fold piece of paper shock cord mount?

Get some zip-loc bags and gift small bags to the other members of your club. You'll never use it unless you start an elastic cord macrame class.I was tired of never being able to lay my hands on a sufficient length 1/8” flat elastic shock cord when I needed it.
So I bought a 170 yard spool of it for $10.
The excess elastic shock cord will be distributed as part of my estate.

Yep. Amazon. 1/8" 3mm White Braided Elastic... https://www.amazon.com/dp/B0BBW3DVTQ?ref=ppx_pop_mob_ap_shareI buy the same thing off amazon in various sizes. You'd be shocked how fast you go through it.
The best part is that they have both 1/8" and 1/4" at a relatively good price. They are nominal sizes with 3 and 6 mm.Yep. Amazon. 1/8" 3mm White Braided Elastic... https://www.amazon.com/dp/B0BBW3DVTQ?ref=ppx_pop_mob_ap_share
Plastic coffee stirrer! Cool trick!Long drill bit. Drill up from motor mount, and glue in a plastic coffee stirrer. Loop kevlar over the MMT and up thru stirrer tube.
Makes inspection and future replacement easy too.
You want to try and avoid using the tri-fold (tea-bag) paper shock cord mount altogether. This is because it potentially impedes the movement of the recovery system.How do you attach the kevlar in an Estes kit that uses the tri-fold piece of paper shock cord mount?

That is good stuff also.Amazon has cotton sheathed elastic in 1/4 and 3/8 in bulk. https://www.amazon.com/gp/product/B004KVTS44/
I haven't found it in 1/8 anywhere.
This post discusses why cotton and links to a source with neoprene elastomer instead of the latex used by Dritz in the Amazon link above.

The Estes tri-fold works fine with Kevlar and lets you use that style mount in tubes as small as BT-20. Or at least it lets me do that. It's more secure (but thicker) if you do it the original way where the shock cord is folded twice but is OK with the current way it is shown.How do you attach the kevlar in an Estes kit that uses the tri-fold piece of paper shock cord mount?

Don't strippers use that?Check this out. This is 1/6 inch (4mm) flat elastic from Amazon.
100 Yards - 1/6 inch (4mm) Flat Elastic for Sewing https://a.co/d/8dXXOss
100 yards. Would have been nice to be on a spool. Check out the weird “braid” when stretched.

Yes, it seems more decorative than strong. Still, I pulled on it pretty hard and it did not break.4mm is ~5/32. Weird size. Looks probably weaker than standard 1/8-in elastics.
