Today's InstaMorph idea comes from Joe S. Thanks Joe for the great idea and the fabulous pictures:
"I received a jar of InstaMorph this week from Amazon, purchased on a whim. I've worked with plastics professionally and wanted to mess with it. Actually, I was searching Amazon for a suitable cargo net for my bike's rack but found nothing, and decided to make one, custom fitted to the rack.
So, today I bought (Walmart) some thin nylon rope, and a dozen of these bungee tarp tie downs. But the ball-ends were wrong for my needs. Hooked ends would be better...
Having already played with InstaMorph a little bit, I was aware of it's strength, and wondered if it might make a good hook... hmm...
Getting to the point, it is plenty strong in relatively thin sections, and it will grab and hold onto bungee cord (or rope) as long as the cord has a knot on its end. That knot is critical. Stretch bungee or rope and it's diameter shrinks, and it will slip out unless it's knotted.
Also, it's springy. So, I tried an integrated spring safety-clip, and that worked out well.
One pic shows a break test. I hooked it to the bumper of the car and pulled .. about 75-100 pound pull is my guess.. The hook survived. The 3/16 in. bungee cord broke. The knot remained imbedded in the hook.
These hooks aren't difficult to make.. this was my first experience with the stuff... but don't use this in the trunk of a car. Trunks have been known to hit 170 F in the summertime.
I haven't completed my cargo net as of yet. I may add colorant.. or build a mold so the hooks don't look so obviously hand made. I dunno.. but I know it will be fun.
Thanks for your informative web site. I was pretty much clueless and it got me started."
