Source for smaller tubular nylon?

[Zyzzyva1000]

I have been building a bunch of smaller mid power rockets with spare parts and 3D printing, and am looking for a better (cheaper) source for shock cords. I have spools of kevlar that I use for a harness, but usually just run a loop to just before the end of the body tube, and then attach a shock cord to that. Yes I could use kevlar for the whole cord, but I really like the LOC 3/16 tubular nylon. However I don't need sewn loops (I make them myself) and I would like to be able to make custom lengths (and presumably if I can find a large spool I can do it cheaper too).

Having some trouble finding the same material that LOC sells. Everything is either flat webbing, or paracord. Maybe I am just searching for the wrong term? I like the 3/16 tubular nylon because it's lightweight and packs well in smaller rockets. I have some speed rope stuff I use in larger rockets, but it gets bulky. If anyone knows where to source something similar to the LOC product, it would be much appreciated.

I've bought nylon strap material from https://www.countrybrookdesign.com/ but about the smallest they have is 3/8"

Fly Market Kitmaking Supplies has a 3/16" nylon "braided lacing". that might work. It's not tubular, more like webbing.

I use good quality elastic on all my lighter MPR rockets. 3/8 elastic would work just fine, much more forgiving also for that less than perfect deployment.

Bookmarking this one! That should make excellent shroud lines for chutes up to at least 60" and at $0.25 a foot!

Thanks...

Yep. After a LOT of looking, and contacting suppliers...This is the ONLY place I found selling 3/16" tubular nylon. But they will NOT give a strength rating of their cord.

LOC rates there's at 375# I have been too busy to setup proper testing to get a comparison. For LPR and Small MPR this material is fine.

Used to go to Bass Pro Shops and buy tubular nylon there.

Indeed, this was exactly what I wanted. And since I don't care about color, purple it is. Thank you much!

I've gotten lots of tubular nylon at REI. They will cut if to length for you.

Do they have the 550 coreless / 650 paracord? That's kinda what this thread is about. You can get bigger stuff almost anywhere.

I bought a 1000 ft. roll of 550 paracord years back when I built my chute for my L3. I just tried to pull the core out of 20ft & 30 ft. pieces of the 550 and if you can get ahold of just the core, it pulls out pretty easily leaving a flat tubular nylon about 5/32" wide when flattened.

I would just look for the color and pattern I wanted and get either the paracord or the gutless paracord and pull the core if you have to. It's pretty easy to do and both types run about 10 - 12 cents a foot.

Well, I don't know about all their supply. I just use their 5/8" climbing nylon for shock cords. It's worked well for me for up to 4" HP.
I did reread the original post and the LOC 3/16 is too weak in my opinion. I had one LOC rocket with that and after a couple of flights it burned thru causing a an expensive 'recovery'. (EDIT) I upgraded it to Kevlar.
