Thanks Joy. Yep, that pretty much describes what I watched on the videos I saw. Your descriptions are right on.
That's the method I watched, and tried (unsuccessfully so far). I'm familiar with the legs / center pin / rubber insulator method. That's the same set up as my Joytech CLR coils, which I'm very familiar with. The CLR coils use a horizontal coil, which I find much easier than the vertical builds.
I'll use the little Nautilus RBA's for as long as they last, but it's always nice to have a plan B to fall back on.
I'll keep practicing with the BVC rebuilds.
Thanks for the tips!
