Thanks for the feedback folks. Kind of backwards, but while I have a dremel, I don't have jewelry files, lol. I do have some round diamond bits for it, so I'll start with that instead of a cutting disk and just work on the channel on the deck. I'll take it slow and try that. I'll just increase them slowly until I get where I need to be. I've actually got a total of four decks (found another today), so if I screw the first one up, I'll get some jewelry files.
I vape unflavored juice, so my factory SSOCC coils usually last about a month, haven't been in a bit hurry to start building my own for that reason. Would be nice to know I can build and get a good vape though if I have a problem finding the coils I want down the road.
Thanks again.
