Some mention has been made at times for using the yellow heat-shrink crimps for attaching leads, etc. I tried them out. They work real easily and are readily attainable. Has anyone had a problem in soil or in any various applications? I noticed the crimp takes a little knack to get used to it--too hard and you may puncture the insulation, too light and the wire can come out. But it seems like a great way to add on leads. Also, holy crap, I tried Mike G's method for heat-shrink: MAPP gas. Same thing, easy, fast, portable, but you have to practice to get good at it (very hot, can burn insulation easily). I like it. But not for building mounts. I'll just keep using the heat gun fun that.
