Shorting Coils

[CallmeB]

So I see lots of ppl pinch and torch their coils on youtube to make them stay tight. My question is: won't this make the coil short? Here is an image I made to more clearly show what I mean.

You torch the coils to make an oxided layer so it doesn't short.

I thought of that too. I sand the legs of my coils with 400 grit sand paper to ensure they make proper contact, but I'm not sure that the inner parts of the coil would oxidize, BUT I have done a test with 2 equal size wires wrapped equally and torched one and the other I left untorched. They both measured the same resistance. That doesn't prove that the coil's don't short when compressed, but it is evidence that they don't.
