I'll have to look for those the next time I'm in Lehi. Cabela's is an awesome store anyway.

Most of mine look sorta like this:


They have the locking snap as shown here, but have a simpler swivel section sans the fancy bearings. I don't think these are as good as the ones Bob cited, but their locking mechanism is still better than nothing.

I only use these on birds up to ~E power. After that, I use quick links. At that power level, the added bulk and mass of quick links is no big deal.

These are called duolock-style snaps. The various versions of these at Cabela's website don't seem to have test numbers that are as high as comparable coastlock-style snaps, not even the ones made by SPRO. This style is somewhat easier to find in stores, though. I have gotten most of my rocketry-related terminal tackle in the fishing departments of K-Mart and Walmart. :rolleyes:

Also, a friend of mine once warned me that the two tabs projecting out the side of the duolock-style snap could catch and snag on parts of the recovery system. It sounds plausible, but I have never seen that actually happen.

I have to confess here that most of my snap swivels are of the common brass "safety pin" style. :o I really should replace them all with well-made swivels that have coastlock snaps.

I really wish I could find 1/16" or 3/32" quick links. :( They would really fill a niche for me in my MPR builds. But I could probably do just as well (maybe even better) with the larger snap swivels made by SPRO.

From my experience, the size of the swivel depended on the size of the chute lines, for the estes chutes with small twine, the little swivels work well, but on my bt-80 upscale fiesta and top-flight chute, I used a very small key ring to secure the chute to the eyelet, and it worked well, but it didn't swivel. Didnt really NEED to swivel, but would have been nicer if equipped with one.

Yes, I've used ones like this, and they do work OK, at least on smaller models.

Okay - rookie question here - what are "quick links?" I have the better snap swivels for smaller stuff, but I also have some HPR to build, and want to make sure that I'm using stuff that's up to the challenge.

And while we're at it - where are some good places to get this stuff, even the larger snap swivels. The local Walmarts only have the itty bitty stuff that barely passes for the Estes style chutes.

Thanks,

Paul

Perfect Answer!

Paul,
One of the best places to find "quick links" is at your local Home Depot or Lowe's store.
Be aware though that some stores I have been in did not have them, but most do.
Any "olde tyme" style independent hardware store would have them if they are worth a hoot.
