28 will always be thicker and easier to deal with than 32. make sure when you are catching the 32 in your posts that you have your bit in the coil and don't over tighten. that will deform your coil as well
To get that high with a single coil you're looking at quite a few wraps around a decent thickness core with a higher gauge Kanthal. Say 10 or more around 3mm of 32 gauge. I don't have the resistance per foot info in front of me to calculate the exact length necessary.This thread made me a believer, now on order as my first rebuildable, but I have an odd restriction. Could you rebuildable pros suggest how I can obtain a coil between 2.0 and 2.5 ohms? I'm not familiar with the gauge and winding conversions. I have and can use a meter. I'm fine with a single coil so that leaves more room for a bigger coil, and if I raise the coil closer to the top of the cone, the airflow should be okay for both holes (from what I'm reading of your experiences). I don't like an airy draw so I may get by with a single hole (and move the coil over the one I don't plug up with 100% silicone).
Another problem I'm having is tightening up the coils on the screws. When I start tightening them, it starts to warp the coil builds. Should I be going clockwise or counterclockwise when wrapping the wire around the screw?
@BNEAT, You have the best icon ever, I love that light, look at it everyday...
So 'soaking in alcohol bath' means you drop all the parts into a glass of isopropyl rubbing alcohol? Is that better/worse than cheap vodka?
