Re: Snake problems

I've been pulling weeds in the veggie-garden most of the day (my 4th gig was on Friday… got that out of the way early on)... and have been trying (while pulling weeds) to get my head around this phenomenon: why the jacket of a snake pulls back when a snake is twisted. Of-course, when something is twisted, it gets shorter... at least till stuff starts to break. Anyhoo... It stands to reason that the outer conductors (of a snake) would shorten more-so relatively in relationship to the inner conductors... and of-course, since the outer jacket of a snake is in contact with the outer conductors... the jacket will be pulled back when the outer conductors relatively shorten due to twisting the entire bundle. I believe the problem is compounded when the snake is laid in the sun, heats, everything somewhat normalizes in a twisted state... the copper conductors stretch out, but the jacket doesn't... metal tends to push metal, where-as PVC doesn't really push PVC, the PVC just gets a little fatter. And then it's further compounded when the twisted snake is coiled and stowed, and cools down... kind of does a Chinese finger trap sort of thing where the conductors shrink somewhat, the outer jacket stayed in place where it was at when the snake was hot... then when the whole mass cools down and shrinks some, the contracting outer conductors pulls the jacket back a little more (repeat a few dozen or hundred times and it gets ugly).

Anyhoo... probably the best way to avoid whatever it is that gets the jacket out of sync with the conductors when a snake is twisted and repeatedly heated and cooled is to just keep the twists out of the snake.

BTW: I personally believe that a few twists in a hundred plus foot snake probably isn't that big of deal... but I have had snakes sent to me for rehabilitation (numerous mfg. brands) where there was on the order of a twist every couple of feet the entire length of the snake... and basically universally, twists in a snake of that magnitude caused problems that were pretty much hopeless.
