to me there is nothing "wrong" with a spaced coil, I do spaced coils too
it's not that a spaced coil can't vape well, it can, it's just that a tight microcoil does add something to the vape that you can't get any other way. it's not something that is absolutely necessary for a good vape and there are many people who enjoy vaping that have never experienced a true tight microcoil and that's fine, there is more than one way to vape and I'm not looking to say here that any other way is wrong, all I'm saying is that a tight microcoil does add properties to the vape that you can't get any other way, and it is a very enjoyable vape, it adds a certain quality to the vape that you really have to experience to "get it" and also that any gap in the coil negates this "effect", enough small gaps and this "effect" is nullified. does anyone really NEED this effect? no, but that doesn't make it any less enjoyable when you do achieve this effect.
mactechvapor attributes "the effect" achieved as being a result of the electrical properties of the wind and believes that the tension imparted on the wire does something to the electrical properties of the wind. personally I don't share this view, personally I attribute this effect solely to the mechanical aspect of the wind and solely to the close tight proximity wraps. to me the electrical aspect ends once the coil is oxidized, to me once the coil is oxidized to the point of no shorts and even firing then the coil is stable, as stable as if it was a non contact wrap, but where the effect comes from is a result of the vapor being forced through these tight close wraps. the vapor is diffused, it doesn't shoot out of the coil at high velocity, it instead kind of just bubbles and froths from the coil and this creates a very distinct change in the vapors flavor production.
I have done may tests and analyzed many builds to form these conclusions but in the end these are nothing more than my own theories and conclusions. I do happen to believe my own conclusions but I'm not arrogant enough to state them here as being facts, there more of my own personal beliefs and conclusions than factual absolutes but from many tests and samplings I do believe them to be in fact true, yet I'm still open to considering other theories and realize that as much as I may think I know, in the end truth is there is probably many things going on here that I can't possibly "see" too so I can only go by what I can observe.
here's a shot of some testing I have done, to compare exactly what this "effect" does...
here I have made 2 tight micro's, vaped them as-is for a day or 2, then simply stretched one out to no longer be a contact and noted the differences in the vape
experiments like this will help you to really see the differences, differences in the vapor coming off of the coil, differences in heat up time, differences in gunk build up and differences in the vape itself. I encourage anyone who really wants to delve deeper into understanding how coil differences affect the vape to experiment and try different things, to play around and experiment. play with coil configurations and positioning and any other variables to learn how any small changes affect your vape. sometimes the difference between an ok vape and a killer vape can be in very small changes, understanding how these small changes affect the vape is a great way to dial in your own ideal killer vape...
in the end I believe that getting a good vape is easy enough but fine tuning that to a great vape is where the finesse and fine tuning comes into play, and understanding what is going on and what small changes affect the vape can go a long way towards being able to always set up a great vape for yourself VS the hit and miss many go through.. how many have just all of a sudden hit on a really great vaping build only to then be afraid of touching it because they are afraid they may not be able to duplicate it again. they don't know exactly why this particular build shines above there others but they know that they will loose it when they rebuild it. my goals are to identify the variables and be able to reproduce that killer vape each and every time. my coil spinner goes a long way towards achieving that for me. it's far from the only way to do it, it's just another tool to help and for me personally it's the only way to wrap because it's the easiest way and gives the best results, consistently, each and every time. I don't see any reason to do it any other way for me personally
