Thanks @antonherbst
I generally do contact coils too. In my early days with the RM2 i was getting quite a bit of spitting with spaced coils and i didnt like it. Maybe my wicking wasnt good enough and maybe i should have persevered.
It was @RIEFY that famously showed us a few years back how in theory you get more surface area with spaced coils because the wick bumps up against the sides of the wire in the spaces. And he showed a great photo once which was intriguing. I still want to experiment more with spaced.
I believe its not difficult to do spaced. You just do a normal contact and then when its still on the mandrel, you pull it apart quite a bit, then push it close together. When you let go, there are spaces between the wraps. And you can "pick" at it with a sharp tool to even out the spaces.
I want to try spaced coils in some of my devices. Its on my todo list
It seems as thou the to do list never ends in vaping. I have a few things on my list and its not getting any shorter. for now the tight coils works wonders and why change when something works. One day when i find a change i will do it. Until then plain tight coils in all my setups running between 0,5 and 0,7 ohms.
