Hey folks. Been vaping for a while now, knowledgeable in ohms law, safety, etc. I love my standard 20 gauge 5 or 6 wrap duals around a 3mm bit. I prebend for center post and readjust for height when screwed down. But I have run into issues recently. I've bought and destroyed the center post on nearly 4 tugboat v2s. Basically when building a center post build, or standard build for that matter, the center post expands and warps due to how stiff the metal is or maybe I'm tightening them down way to much. I tend to be OCD about the coil build and need it perfect so that may be my problem. I have tried numerous RDAs but I'm used to building on the tugboat and love everything about it, pluse I have all the topcaps and replacement center pins and insulators. I figured that the three post design may be the problem so I went with a Petri 1.5 and still cant get it to how I like it with 20G so I've started attempting to build fused claptons to get a similar vape but with more pliable wire. I was just looking for any advice possible on anything I have discussed. Also I think the center post on a tugboat should be stronger with all the cloud chuckers popping up with their products. Any and all advice would be greatly appreciated.
