Like so many other elements of this hobby, there "can" appear to be a great deal of mystique surrounding Mesh and Genesis Mods.
I well remember when I first joined POTV I was dumbfounded by some of the seemingly incongruous responses to questions being asked back then and nearly gave up before I began. However, whilst it was a steep learning curve at the time, it paid off in spades. It was a case of not quite believing how simple it had been and being absolutely certain that I had done something wrong because it worked!!
This was long before we had the so much more straight forward devices that VapeWareMods gave us, such as the NextGen. My first Mesh building experiences were with the Kracken and some other awful piece of garbage.
@rew The NextEra is somewhat different from the NextGen and Nextiny in that you don't have the Upstand in the deck onto which you build your Mesh Wick. In many ways, I now find the NextEra by far the easiest to work with and certainly the quickest. The one tip I would give you is to make your coil at 3mm id and then you have plenty of room for inserting the Mesh Roll.
There is an exceptionally good Build Guide here...............
