I have a magma also, and want a 1.5 coil. I am using a provari. I have 28, 29, and 30 ga wire. Can you suggest which one to use and how many wraps? And 1/16 or 5/64" drill bit?
With a micro coil 6 or 7 wraps 30ga and 9 or 10 wraps 28ga on a 5/64" bit should get you there. There's a page floating around somewhere with different builds/ohms but I cant find it at the moment. I just chart my own as I make them and use that for reference.
