ADC - Nice Rebar stakes - are those the stakes you use for snare and kill pole? what is the nut at the top for?
Yes they are for Kill Poles. The end of the snare goes up through the nut then cinches down on the top of the stake.
You might be right on some things but baking soda Isn't going to make 1x19 any stiffer. I know for a fact since I use It.
Boiling the cable, even just simmering it a little, will remove the oil from the inner strands of the cable. Once this lubrication is gone they will start to corrode, (how fast and how bad depends upon climate), but even the slightest causes friction between the strands of cable. This friction causes the cable to be more rigid and doesn't bend as smooth and easily. In your case you are using a very stiff cable to begin with (1x19 3/32") so you may not notice a really significant difference but I'll guarantee the cable is at least minutely stiffer. It's not going to keep you from catching coyotes but it can cause them to get a little further into the loop before it fires shut... and this, while no big deal with CR's, can be make a huge difference in the effectiveness of kill snares. They are much more effective when closed right below the skull, vs. further down the neck. Now, I know, the OP was asking about CR's so this part of the equation may not be of as much value to him, but there are a lot more folks reading this that it might help. In the case of the OP the coloring of the restraints so they blend better to their surroundings is the more valuable part of the light dusting of spray paint vs. boiling them in soda.
