I have had my vulcan for about 3 weeks now and I really enjoy it. Been doing single wire dual coils, both vertical and horizontal builds, and so far my best build was a twisted 28 gauge that came in around .6 if I recall correctly around a 2 mm drill bit. What's everyone else doing with their vulcans? I'm willing to build down to .3 to .4 on this as it does get very hot.
