My wraps are all spaced coils. I've tried contact coils using a Kuro Koiler and I prefer spaced coils more. With the wide dual post, doing a spaced coil is easy. I've done single coils (when I was using nickel) in the Velocity between the two posts but the biggest pain is putting in those 90 degree bends in the coil legs. Here is a pic of a single coil build sitting in between the posts.Thanks you guys. Yes, I do want to sub ohm. I'll try both of these. So, what if I wanted to do the single coil between the posts? Maybe use a twisted wire to wrap it? Would that get me low enough using this 26 gauge with just one coil? And, are you talking about spaced wraps?
