Very well then. Oddly enough, so am I; although I'm engineering, not physics

Over to you. If you have a solid understanding of Ohm's Law you know what you're doing. I do want to repeat my advice about good batteries from a reliable vendor. I really do like the Sony VTC4s in mechanical mods, and these are often counterfeited. If you'd like a recommendation as to where to buy, sing out. You said you "ordered coils," did you mean pre-made ones? I wind my own which is part of the fun I think. You'll find an excellent coil calculator in
Steam Engine if you'd like to try. There are also good coil tools available, but I started on drill bits just for an accurate diameter. I find the heat flux section off to the right of the calculator to be of particular use in finding a good build; doubtless you will understand it at a glance. I am of the opinion getting a good build in a mech is more art than science. Not that it couldn't be calculated, but that all the data are not known. I find I build and build again until I get what I want and then try to repeat it next time it needs it. You also ordered cotton, and that's good. I started there also. However, I have lately made the shift to cellucotton/rayon. I think it wicks better and tastes better. Again, ask away for tips and pointers, and welcome to the wonderful world of mech mods. I have been a mekkie for some time, and I love them. Finally, if you feel an apology is in order for the tone of my previous post, be kind enough to consider one extended. I'm sure you understand my concerns, however. We get a lot of people around here who really don't know what they're doing. I could tell you stories... we had a dude just today, using a faux-hybrid mod-- where the 510 just screws in to the top of the mod and directly contacts that battery-- without enough clearance between the outer threads and the center pin. He wanted to know what the black marks were on the top of his battery, God help us. Having the math, I understand what releasing the energy contained in an 18650 in a few microseconds within a confined stainless tube inches from the face would do. Surely I have had that nightmare enough

Vape on, vape safe and vape happy...
