Best knot for rubber shock cord?!

So I did some searching and did not really find anything definitive about what is the best knot to secure rubber shock cord, like what comes in LP kits.

I did some experimenting the other night and tried the usual double overhand knot. Then pulled on it pretty good and guess what? Well you know it came apart! I thought well maybe smear some wood glue on it. That seemed to help.

But then I threw back to my sailing days and thought "Why not try a Bowline knot". Did that and pulled until the rubber snapped! The knot was still intact!

From now on that is the knot I will be using

Oh here is a video on how to tie one!

I always just use slip knots

The bowline is my knot of choice for that, and many other things. I usually cable tie the loose end to the non-loop part as well, just to be sure.

I don't use rubber shock cords....period, but for other shock cord materials a bowline is generally what I use as well.

I use bowline, square knots, and alpine buterflies (great if you need to attach something in the middle of a shock cord)

Haven't tried it yet but considering using double fisherman's knot for linking kevlar to elastic in the future.

Micromiester had a few knot threads that should be around the forum somewhere.

I use the bowline as well. You can tie it at any location on the cord, it's not limited to just the ends.

I also use bowlines for shock cord to nose. For rubber to Kevlar I sometimes use two bowlines, one in each line with the loops through each other. But I sometimes use a sheet bend.

If you are tying a knot in rubber strip, lubrication is necessary. Saliva works well. I know of what I speak after making up hundreds of rubber motors for free flight model airplanes. I use a simple water knot to join the strip.

Now the use of rubber strip for shock cords is another topic entirely I wouldn't use it for that purpose myself.

By the way all of the knots I use in rocketry are the ones I used rock climbing. I figure that if I'm willing to trust my life to them they are good enough for rocketry!
