Anyone ever deal with Twin Line for Kevlar shockcord material

[Bill S]

I'm looking to get some Kevlar line for shock cords for my low powered rockets. I had been buying it in 50ft pieces from Erockets, but I wanted a cheaper source. I found Twinline, and it looks like the Kevlar is US made, which is a definite plus over cheapo Chinese cord.

Just wanted to see if anyone has dealt with them before. Thanks.

I'm thinking of this stuff:

I use their braided spectra for my big kite. It is an excellent product.

Thanks. Ordered a 250 foot spool of their Braided Kevlar to try out.

Those are good prices. What's shipping like?

It quoted me $5.40 to my home, which is not bad at all.
Net of shipping, cost is comparable to (slightly cheaper than) Emma Kites off Amazon.

Over the past few years, I've ordered 4 spools, of various thickness and strength, from Emma Kites (free shipping).
150lb for low-power, 700lb for mid-power.

I bought a 250 ft spool of the 110 lb braided Kevlar for $5.60 plus $5.40 shipping, total $11 to PA state.

After action report on the 110lb braided kevlar line from Twinline. The material seems to tangle easily; even when I was adding the kevlar shockcord to my Estes Vapor, it seemed to want to tangle up and knot itself. I should have paid more attention to this clue, because when I launched the rocket yesterday, the kevlar line knotted up in a big rats nest and prevented parachute deployment (which ended up wrapping itself around the rear fin area), and the rocket did a tailfirst descent, damaging the body tube badly.

When I went home, I threw away the spool I had bought. It was false economy hoping to find a cheaper product that worked as well as what I had been previously been using.

I have never had any issues with the previous kevlar I was getting from Erockets, and so I think I am going back to that, even though he only sells what I want in 50 foot packages.

I'm sorry that happened, but thank you for reporting the results.
