Just tonight, I used to be chatting with some rocketry pals by Zoom, and one of the extra senior guys holds up a couple of items destined for his high energy rocket. He's asking for help and advice on tips on how to proceed.


He's received a medium sized carabiner in his right hand, and in his left is a strip of what he is asking an elastic band. (It appears more like the headband woven elastic band that Spock wears in Star Trek IV: The Voyage Home, but irrespective of.)


It's a long length or Elastic band cheap skein of two inch wide elastic band that looks like it might either go in a truss, a bra, jacquard elastic webbing webbing or some type of again brace.

And he's asking, "How do I attach this to that?"

The discussion starts and guidelines out sewing (cause the stitches will not stretch), rivets (cause they will pop whenever it stretches), grommets (for a similar motive) and glue, (as it won't "give" with out cracking).


One rocketeer mentioned, "Dump it, simply get a nylon rope or similar woven tube, and tie it on", just as you'd in mountain climbing.


We all pretty much agreed that the two inch width of the elastic band won't enable for a tight knot to be tied across the carabiner, so we settle on the nylon tube/rope thought.


Now this began me thinking in regards to the time that I thought-about making my own shock cord out of elastic. I used to be doing a scratch construct for a recycling show on how you could possibly flip atypical trash into a very simple rocket and nosecone with plastic Wal-Mart bag parachute. For a shock cord, I had settled upon an outdated pair of men's tighty-whitey briefs.


I satisfied my wife to lend me her pinking sheers, and i used a seam ripper to free the elastic band from the pair of shorts. Very quickly, I tired of the seam ripper, and went for a straight sharp pair of fabric sheers, and just minimize as close to the waist band as I might.


Now that I had the loop of elastic free, I don't recall if I lower across the seem or ripped it free, but I wound up with a single length of one inch wide elastic that still had loads of stretch in it.


Deciding that the band was too huge, I took the fabric sheers and minimize down the center of the band leaving an equal width of elastic band on either facet of the minimize. What I hadn't counted upon was the fraying, which began instantly. The two elastic strips, whereas about 42 inches long, curled and buckled, refusing to put flat.


This was symptomatic of how the elastic band would behave irrespective of how I minimize it , stretched it, or steam pressed it. I learned that you simply Can't minimize an elastic band lengthwise had have it work. (Now, for the purposes of my poster board display of the elements of a rocket, it worked well sufficient, however for actually use in a rocket, my concept wouldn't have worked.)


What WOULD work is the acquisition of about three feet of slender 1/8-1/four inch elastic from Joann Fabrics or related store. Except for the run on this material to make masks in the course of the pandemic, this is able to work for smaller, low-power rockets should you needed to substitute a shock cord.
