Lifted from the thread TENSION WRAPPING | Post #5 for reference here…
Aside from slightly changing the resistance of the wire, does tension wrapping your coils affect the wire's performance in other ways?
Taking into consideration the gauge and amount of tension applied.
@muth, good question. The resistance changes very little from the slight amount of stretching. Wouldn't be saying much if that's all there were to it.
Straining wire precisely on a mandrel though is just the means to an end. One similar in functional practice as curing a good cast iron pan. A slight strain multiplied by a good tool like a pin vise builds form into the wire as in a spring with very little effort. Coils then just want to stubbornly be one. Getting it
just that tight and symmetrical aids tremendously in uniformly oxidizing the surface with electrical pulsing of the battery. Quickly, so less fiddly time getting to the vape. It's these two things, persistent form and the resulting wire surface insulation of alumina that take the final form
much, much closer to the "theoretical" resistance of the wire. In other words, you make the most of the heat from the pan.
So you can make good tight winds that outperform a larger heftier geometry by bettering even heating. Much as you might by concentrating the light of several magnifiers. Except it's
not random or variable but consistently (focused) and so a lesser likelihood of scorching wick and flow. I'm sure you may appreciate what such a uniform effective surface can do in the kitchen if you enjoy cooking as I do.
My reluctant surprise five years ago was just how well it worked. If interested, give us a shout. I'm here to help if need be in getting the wind and prep right. In the middle of a project but I'll do my best or someone should pipe in on the above thread.
Good luck muth.
p.s. For clarification, straining a wire stretches it if ever so slightly. But in so doing it's made
thinner accounting for the small changes in linear resistance.
